Smart Casual Dress Code for Men: The New Rules

Smart casual is one of the most commonly misunderstood dress codes. Its vague nature often leaves people wondering what exactly it means. Balancing formal and casual elements can feel tricky, especially when the boundaries aren’t clearly defined or explained.

However, understanding its principles makes it easier to craft stylish and appropriate outfits.

Smart casual is a style of dress that combines elements of both formal and informal clothing to create a polished and relaxed look. It’s seen as less rigid than traditional formal attire but more refined than casual wear, striking a balance between sophistication and comfort. This versatile dress code is often used for events or occasions where full business attire would feel too stuffy but casual clothing would appear too laid-back, hence the mixed name.

What defines smart casual?

Mr Porter

Smart casual is a dress code that blends formal and casual clothing elements to create a polished yet relaxed look. It’s versatile and aims to strike a balance between the structure of business attire and the ease of everyday wear. But unlike strict formal dress codes, smart casual allows for personal style while maintaining a sense of refinement that stands above what you’d normally wear when going out with friends or lounging around at home.

Some of the key components of smart casual outfits include tailored pieces like blazers or chinos, combined with more relaxed items such as polo shirts, knitwear, or clean trainers. Neutral colours and high-quality fabrics play a significant role in creating a cohesive and sophisticated appearance too. Accessories such as belts, watches, or scarves can add subtle flair as well without overwhelming the outfit.

Smart casual is usually seen on occasions where formal attire would feel excessive, yet casual wear would be inappropriate. It’s perfect for workplace settings, dinner dates, and casual weddings.

What isn’t smart Casual?

Mr Porter

To keep things simple, smart casual isn’t the same as everyday casual wear or business formal clothing. Certain items and styles are generally unsuitable for this dress code, as they detract from its polished aesthetic.

For example, anything that is ripped or distressed doesn’t suit the smart casual look. Wearing anything with a graphic or print that screams “look at me” also isn’t a great look for smart casual. Any kind of sportswear, including hoodies and trainers, also isn’t good for smart casual. And lastly, it’s important to look for well-fitted items that don’t look baggy or oversized. When it comes to footwear, you also have to avoid any kind of sandals, flip-flops, crocs–that sort of thing.

In short, you have to avoid overly relaxed or messy styles, as smart casual should always feel deliberate and well-put-together.

The Evolution of Men’s Smart Casual Dress Code

Mr Porter

There was a time when smart casual just meant swapping the sneakers for some leather shoes, throwing a blazer on and calling it a day. Many men still treat the dress code this way today, but to take this approach is to do yourself a disservice. There’s so much more that can be done with smart casual, particularly now that dress codes have loosened up and begun to spill over into one another.

It’s not exactly clear where the smart-casual dress code emerged from, but what is certain is that it has changed a great deal over the years. Before the 1950s, the term was used to describe slightly less formal suits than those worn in the office. As the concept of casual wear developed, and garments like T-shirts and jeans became the norm, the dress code took on a slightly more relaxed, semi-formal feel, blurring the line between workplace attire and weekend wear.

It’s a fashion trend that has continued ever since, with more casual and sporty elements creeping in over the years, to the point that it’s now perfectly acceptable to wear things like jeans, polo shirts and sneakers as part of the dress code… provided they’re elevated by smarter surrounding pieces.

How to master the smart casual dress code

Let’s start with a blazer

Mr Porter Blazers

A blazer is one of the most versatile pieces in the smart casual dress code for men. It instantly improves any outfit, making even the simplest combination of a shirt and trousers look polished and refined. A blazer adds structure and refinement to an outfit, bridging the gap between formal and casual. The fit and colour of your blazer are critical as anything too loose or bright can make your outfit feel off and a bit too casual. Sticking to timeless, neutral tones ensures your blazer will work with a variety of outfits and occasions.

To make the most of this piece, invest in an unstructured blazer in a colour like navy, charcoal, or beige. Unstructured blazers are more relaxed than their formal counterparts but keep the sophistication needed for a smart casual outfit. Pair your blazer with chinos or dark jeans for a balanced look. For shirts, an Oxford or a simple button-down in white or light blue works perfectly. To complete the look, add loafers or minimalist trainers for a contemporary touch.

When in doubt, add chinos to your outfit

Mr Porter Chinos

Chinos are an essential item in smart casual wear for men as they offer a polished and comfortable alternative to jeans, and they’re a more relaxed option compared to tailored trousers. They’re versatile, comfortable, and can be dressed up or down depending on the occasion. Chinos have a semi-structured fit which makes them perfect for creating a sleek silhouette without looking too formal. The right fit is crucial as baggy chinos can appear unkempt, while overly tight ones feel restrictive.

When shopping for chinos, focus on slim or tapered fits that follow the natural shape of your legs. Neutral colours like beige, navy, olive, or grey work best for men’s smart casual outfits, as they pair well with a variety of tops and footwear. Style chinos with a polo shirt for a relaxed daytime look or a crisp Oxford shirt and blazer for an evening event, then add loafers or leather trainers to finish off your outfit.

Dark jeans for a refined look

Mr Porter Jeans

Dark jeans are a cornerstone of smart casual men’s outfits. Unlike lighter denim or distressed styles, dark jeans offer a refined, polished look that works in various settings. Their versatility helps you pair them with casual staples or more formal pieces like blazers. Fit is especially important for jeans in the smart casual dress code for men, as overly loose or baggy styles look sloppy, while overly skinny jeans can appear too casual or trendy.

Opt for slim or straight-fit jeans in dark washes like indigo, black, or charcoal. Make sure there’s no distressing, rips, or fading, as these features detract from the refined aesthetic of smart casual wear. For a classic look, wear dark jeans with a tucked-in white shirt, a belt, and loafers. Alternatively, pair them with a crew-neck jumper and a tailored blazer for a modern twist.

Choosing the right shirt

Mr Porter Shirts

Choosing the right shirt is essential when it comes to men’s smart casual outfits. Shirts offer a clean and structured base that can be styled up or down depending on the occasion. An Oxford or button-down shirt oozes refinement, making it a better choice than casual T-shirts or printed styles. Fit is crucial here because poorly fitted shirts can ruin the balance between polished and relaxed.

For a timeless wardrobe, invest in shirts made from high-quality materials in neutral colours like white, light blue, or grey. Subtle patterns such as checks or pinstripes can add interest without overwhelming your outfit. Style your shirt tucked into chinos or dark jeans, and consider rolling up the sleeves for a more relaxed look when things feel more casual, then pair it with a blazer or lightweight knitwear to create a versatile, layered outfit.

Don’t sleep on knitwear

Mr Porter Knitwear

Knitwear is a valuable addition to smart casual wear for men as it adds texture, warmth, and sophistication to any outfit. Lightweight jumpers or cardigans in fine-gauge knits are perfect for layering with as well, providing a refined look that is still relaxed. Neutral colours like navy, grey, and beige ensure your knitwear complements the rest of your wardrobe without drawing too much attention.

Choose slim-fitting knitwear in breathable fabrics like cotton or merino wool to maintain a sharp silhouette. Pair a crew-neck jumper with an Oxford shirt and chinos for a smart yet understated look. For cooler days, layer a cardigan over a button-down shirt and wear it with tailored trousers. Knitwear is ideal for transitioning between seasons, making it a must-have in smart casual outfits.

Loafers, a staple for any smart casual outfit

Mr Porter Loafers

Loafers are a staple in smart casual men’s outfits, bridging the gap between formal and casual footwear. They’re sleek, comfortable, and versatile, making them an excellent choice for almost any occasion. The right pair of loafers adds a lot of polish to your outfit without feeling overly formal. Leather loafers are also ideal for the smart casual dress code for men, as they exude sophistication while remaining approachable.

Choose loafers in classic shades like brown, black, or burgundy for maximum versatility. Penny loafers and tassel loafers are timeless styles that pair well with chinos, dark jeans, or tailored trousers. For a more relaxed look, wear brown loafers with navy chinos and a light blue shirt. In warmer weather, consider wearing suede loafers instead for a softer, summery vibe, but ensure they are clean and well-maintained.

Trainers are considered smart casual too

Mr Porter Sneakers

Most people don’t think of sneakers or trainers when they’re putting together a smart casual outfit, but that’s probably because most people see them as sporting attire thanks to all of the branding. Believe it or not, minimalist trainers can add a modern touch to smart casual wear. Unlike sporty or branded trainers, clean and simple designs can create a casual yet smart and refined element to your outfit. They’re particularly useful for creating a youthful, contemporary look while adhering to the smart casual dress code for men.

Look for trainers in leather or canvas with minimal detailing. White is a classic choice, but neutral colours like grey or beige also work well. Pair them with chinos and a polo shirt for a casual daytime look, or style them with dark jeans and a tailored blazer for something a little smarter in the evenings. Always ensure your trainers are spotless, as scuffed or dirty footwear can detract from your outfit!

Polo shirts are a great addition to your smart casual wardrobe

Mr Porter Polo Shirt

Polo shirts are a fantastic option for smart casual outfits because they combine structure with comfort. With their collared design, polos look a lot more polished than T-shirts while being less formal than button-downs. This makes them the ideal choice for events where you want to look sharp but not overly dressed up and stuffy.

Choose slim-fit polos in solid colours or subtle patterns like stripes to pair with your outfit. Neutral shades such as navy, white, and grey are great choices that pair well with chinos, dark jeans, or tailored shorts. If you’re looking to create a modern smart casual look, tuck your polo into chinos and add a leather belt and loafers. Alternatively, layer a lightweight blazer over your polo for a more polished finish.

Smart Causal Styling Tips

Give both words equal attention

When styling a smart-casual look, it’s best not to lean too far in either direction. Place equal emphasis on the ‘smart’ and ‘casual’ elements of the outfit to achieve a balanced whole. That means throwing a blazer over a tracksuit isn’t going to cut it. Similarly, wearing a three-piece suit with loafers instead of Derby shoes doesn’t quite hit the brief either.

Aim somewhere between those two extremes and you should be bang on target.

Remember that fit is everything

Mr Porter

Fit is arguably the most important element when it comes to putting together smart casual outfits. Regardless of how stylish or expensive your clothing is, a poor fit will undermine your entire look and completely ruin it. Baggy or oversized pieces make your outfit look careless, while overly tight clothing can appear uncomfortable and out of place, not to mention how awkward it’ll feel on your skin.

To get the perfect fit, focus on slim or tailored cuts that follow the natural shape of your body. Chinos should taper gently at the ankles, blazers should fit snugly at the shoulders, and shirts should have just enough room to move comfortably without excess fabric. If you’re unsure about fit, consider taking your items to a tailor or getting custom-made pieces. Properly fitted clothing makes your outfit look intentional and well-thought-out, and that’s a key component of what makes smart casual so smart.

Keep tailoring soft

Forgo the sharp, angular lines of traditional tailoring in favor of a softer look. This will give outfits a more relaxed feel, and won’t contrast uncomfortably with less formal pieces. A padded suit jacket with jeans looks awkward and unnatural.

Swap it for an unstructured blazer instead and the whole thing becomes much more cohesive.

Don’t forget to accessorise

Mr Porter

Accessories are the finishing touch that brings smart casual outfits together. They add a bit of personality and polish to your look without being overpowering, and can even make your outfits look more sophisticated without creating imbalances that lean towards too casual or too formal.

Stick to pieces like a leather belt, a minimalist watch, or a pair of classic sunglasses. These are timeless accessories that generally work well on any kind of smart casual outfit. Remember to match both the material and colour of your belt with your shoes for a cohesive appearance too. Adding a simple pocket square can spice up your blazer, and a lightweight scarf works well in the cooler months. Try to avoid bold or flashy accessories that can detract from the overall look as they should complement your outfit, not compete with it.

Darker = smarter

Take this one with a pinch of salt, but as a general rule of thumb it tends to hold true. Take jeans, for example: stonewashed denim has a much more casual feel to it than crisp raw denim. Darker denim just looks smarter.

It’s not just jeans either. With the exception of shirts, darker pieces – from shoes to knitwear – usually come across as slightly dressier, so it’s always good to factor that in when piecing outfits together.

Experiment with patterns, but don’t go overboard!

Mr Porter

Patterns can add a lot of character to smart casual outfits, but simplicity is still the key concept that you should focus on. Subtle patterns such as pinstripes, small checks, or micro-dots are more appropriate than loud or oversized print designs. Intricate yet understated patterns help maintain the polished aesthetic of smart casual wear without looking too bold, but they also add a bit of fun to keep them from being too dull.

Try to incorporate different patterns through shirts, knitwear, or even blazers. For instance, a gingham shirt in navy and white can be paired with neutral chinos and a blazer for a smart look. Avoid mixing too many patterns in one outfit though as this can feel chaotic. Make room for one patterned piece at a time and keep the rest of your outfit simple so that it doesn’t overwhelm the senses. A minimal approach ensures that your smart casual outfits look stylish and cohesive.

Consider texture

Alternating textures are a great way to give your outfits a subtle touch of character and draw the eye in. It’s OK to have several textures in a smart-casual outfit – nay, encouraged – but try to keep it balanced.

Generally speaking, rough, open fabrics lean casual, while flat, smooth materials look smarter. Try to incorporate elements of both for best results.

Use neutral colours for a timeless foundation

Mr Porter

Neutral colours are a key element of smart casual wear for men because they offer a versatile and timeless foundation for your outfits. Shades like navy, grey, beige, white, and black create a cohesive look that is easy to mix and match. Bright or overly bold colours can often clash and detract from the refined look of a smart casual outfit.

When putting together an outfit, use neutral tones as your base and layer in subtle pops of colour if desired. For example, you can pair beige chinos with a navy blazer and a light blue shirt for a classic look. If you want to add colour, try a muted jumper in olive or burgundy to complement neutral tones without overwhelming your outfit. These muted palettes ensure that your smart casual outfits look polished no matter the occasion, and it’s one of the reasons why they’re so popular.

Don’t neglect footwear

Shoes can make or break a smart casual look, so pay them the attention they deserve. It should go without saying, but your footwear should be clean and well looked after. And that goes double if you’re going down the sneakers route.

Some key smart-casual footwear styles include desert boots, Chelsea boots, loafers, Derby shoes, minimalist sneakers and deck shoes. It’s hard to go wrong if you pick from that selection.

Use clean, dark outerwear during colder months

Mr Porter

Outerwear plays a crucial role in completing smart casual outfits for men, particularly during the colder months when temperatures start to drop to uncomfortable levels. A nice coat or jacket not only keeps you warm but also adds an extra layer of style and sophistication. Dark and clean outerwear in structured silhouettes goes perfectly with the smart casual dress code because of how simple and stylish it can be.

Do yourself a favour and invest in timeless outerwear options like a wool overcoat, a trench coat, or a tailored pea coat. Colours such as black, navy, or charcoal are common and pair well with most smart casual wear. Avoid overly casual styles like puffer jackets or bombers as they can detract from the polished aesthetic. For a sleek winter look, layer a navy overcoat over a blazer and chinos, then finish with leather boots.

Refine the basics

One of the tricks to nailing smart-casual style is ensuring your wardrobe’s core components are high quality.

Simple pieces like T-shirts, knitwear and jeans should be the best you can afford and, above all else, fit immaculately. A chain is only as strong as its weakest link, so make the effort to ensure that even the most basic garments don’t let you down.

At the end of the day, it’s (mostly) about your confidence

No matter how perfectly you assemble your smart casual outfits, confidence is the most important ingredient to make them stand out. Wearing your clothes with poise and self-assurance makes all the difference. From the overall fit and colour to the small accessories and footwear to top it off, confidence is what ties together all the elements of the smart casual dress code,

That’s why it’s important to aim for outfits that make you feel comfortable and reflect your personal style. For example, if you’re not used to wearing blazers, you don’t have to force yourself into something tight-fitting that is completely out of your comfort zone. Start simple with a lightweight unstructured option that feels more relaxed. Afterwards, you can pay closer attention to the fit and invest in pieces that you enjoy wearing with it. When you feel confident in your ensemble, you’ll naturally adopt that polished and effortless look that everyone searches for in smart casual wear.

Smart casual FAQs

Hopefully the information in this guide has already answered your burning smart casual questions. But just in case, here are the answers to some of the most common queries men have about the dress code.

Are jeans smart casual?

Yes, with a ‘but’. Jeans can be smart casual but only if they fit well, are free from holes or distressed detailing, and aren’t too light in colour. That said, lighter washes can work so long as they’re styled well and balanced out with smarter pieces.

Are joggers smart casual?

Categorically, no. Joggers are not smart casual. It’s true that dress codes have relaxed, but joggers are still very much in sportswear/athleisure territory. The next best alternative that’s smart casual appropriate would be a pair of tailored drawstring trousers.

Are shorts smart casual?

Yes, shorts are perfectly acceptable as smart casual in the summer, just as long as they’re not too sloppy. That means a big no to athletic shorts and swim shorts, and a resounding yes to chino shorts, tailored shorts and similar. Remember to invest in some no-show socks, too.

Are T-shirts smart casual?

Not alone. However, a crisp white tee tucked into a pair of raw jeans and layered with an oxford shirt is unlikely to raise any eyebrows. It’s all about how it’s styled.

Does smart casual require a jacket?

No, absolutely not. This is one of the most common pitfalls men run into when approaching the dress code. Assuming a blazer must be worn in order for an outfit to be deemed smart casual will hold you back. That said, an unstructured blazer is a great tool to have at your disposal when it comes to crafting your smart casual looks.

Are suits smart casual?

They can be, but again, it’s all about how they’re styled. A two-piece suit dressed down with some knitwear or a polo in place of the shirt, and some minimalist sneakers or loafers in place of smart shoes will always be a solid option. It’s all about striking a balance between ‘smart’ and ‘casual’ without leaning too far in either direction.

Are sneakers smart casual?

These days, yes, sneakers can be smart casual. But they need to be the right kind. Stay away from anything overly sporty, with too much detail or excessive branding. Instead, stick to clean, uncluttered, minimalist styles in premium materials. Again, make sure they’re balanced out by dressier pieces elsewhere in the outfit.

Are polo shirts smart casual?

Much like T-shirts, polo shirts can be smart casual if worn in the right way. Try tucking one into a pair of chinos or dress trousers and layering an unstructured blazer or overshirt over the top.

Are hoodies smart casual?

No, hoodies are not smart casual. If you need something to wear as a mid-layer, focus on knitwear instead. A heavy gauge fisherman knit can do much the same job, albeit without the hood.
