The Art of Dressing Down: How to Style a Suit Casually

Suits have long been seen as the epitome of formalwear, reserved for big meetings, weddings, and other dressy occasions. But in today’s world, the traditional suit is evolving. More and more, men are embracing the versatility of a casual suit, learning how to wear and style a more relaxed outfit.

Why should you wear a casual suit? Beyond the obvious benefits of comfort and versatility, it’s a great way to express your personal style without sacrificing sophistication. A well-fitted suit can be dressed down effortlessly for almost any occasion, whether you're heading to a weekend brunch, a casual day at the office, enjoying a night out with friends or attending a summer wedding.

In this guide, we’ll explore how to achieve that perfect balance of relaxed yet polished with your casual suit. From pairing it with unexpected accessories to choosing the right fabrics, we’ll show you how to style your suit for a more casual look that’s going to get you loads of compliments.

 

What Makes a Suit Casual?

Fabric Choices for a More Relaxed Look:

When styling a casual suit, the fabric is key to achieving your desired look. At Batch LDN, we offer a variety of fabrics that make every occasion feel just right. For ultimate comfort, our brushed cotton suits are a great option—they breathe and feel soft against the skin. They’re ideal for everyday wear, but can also be dressed up to be a little more formal. 

Linen is perfect for warmer days, offering a lightweight and breathable feel while maintaining a sophisticated vibe. Linen can often crease a lot or tear easily. At Batch we have developed a linen blend that avoids over creasing whilst maintaining it’s structure. Our linen casual suits are the perfect wedding outfit. Whether you’re an attendee or the groom, our linen suits can be styled to any dress code. 

If you want something versatile for smarter occasions, wool blends provide a refined look without the stiffness of traditional wool. Hot Batch tip: Avoid heavy, structured fabrics like thick wool or polyester blends, which can look too formal. No matter the season, Batch has a fabric that fits your needs, blending style with comfort all year long.

 

Color & Pattern Selection

When it comes to casual suits, the color and pattern you choose can make all the difference. At Batch LDN, we recommend going for lighter, earthy tones to keep your look relaxed yet stylish. 

Lighter, earthy tones like beige, stone grey, navy, and mocha brown are perfect for casual styling. These shades give off a more approachable, effortless vibe. Whether you're at a weekend event or a laid-back workday, these colors help you strike the right balance between comfort and style.

If you're looking to add a bit more personality to your outfit, subtle patterns like checks, herringbone, or pinstripes are the way to go. These patterns add a touch of interest without feeling too formal, keeping your look fresh and modern. You should check out our Herringbone suit options. 

One thing to avoid? Traditional black business suits. While they’re great for corporate settings, black suits can look too stiff and formal for casual occasions. Instead, opt for more relaxed shades and patterns that fit the vibe you’re going for. For example, our Petrol casual suit is the perfect tone of black - not too formal or stiff. Just an effortless smart-casual look. 

Ways to Dress Down a Suit

Pairing with T-Shirts & Polo Shirts

Dressing down a suit is all about finding the balance between accessories and over-doing it. At Batch, we believe it’s all about pairing your suit with the right layers and accessories to keep things casual while still catching the eye.

Pairing with simple white and black T-shirts  is a great way to tone down the formality of a suit. A crewneck T-shirt is perfect for a laid-back, street-smart look. For a little smarter, a polo shirt adds a bit of polish without feeling too dressed up. These pieces help you achieve a relaxed vibe without compromising on style.

When it comes to materials for layering, we recommend fabrics like cotton and linen. These lightweight, breathable fabrics are ideal for layering under your suit jacket. They add a touch of comfort and allow you to move freely without adding bulk.

As for color coordination, keep things simple and complementary. If your suit is a neutral color like navy, feel free to add a contrasting pop of color with your T-shirt or polo. But avoid going too bold—think subtle tones like off-white, light blue, or even soft pastels to maintain that relaxed, casual vibe. A white tee with a Batch suit is always a safe play that looks great. 

With the right combinations, you can easily dress down your suit while still looking on point.

Styling with Knitwear & Sweaters

Jumpers and knitwear are a game-changer when it comes to layering. They’re light enough to sit smoothly under a jacket without adding bulk, so you get the warmth and texture of knitwear without compromising on fit or style. 

Turtlenecks are perfect for a more refined look. They pair well with both casual and slightly dressier blazers or chore jackets. On the other hand, crewnecks give off a relaxed, easygoing feel – great for a weekend look.  Both are pretty timeless, so it really depends on the mood you're going for. If you want to look fancy, go turtle. If you want to look chill, go crew. How’s that for some sound advice? 

Layering dos and don’ts:

Do: Keep your layers slim and lightweight. The key to a sharp look is in the fit, so avoid anything too bulky. A thin sweater under a blazer or jacket is your best bet for comfort and style. You’re going to be too hot.  A nice layer option that we used 

Don’t: Over-layer. Stick to one or two key pieces – no need to overdo it with too many layers that create unnecessary volume. Avoid competing textures too; you don’t want your knit to clash with your blazer.

Footwear Choices for a Relaxed Suit Look

White leather sneakers/trainers - whatever you call them, are a no-brainer for a casual suiting look. They’re clean, versatile, and add a contemporary look to your outfit without trying too hard. Plus, they work with pretty much any casual suit colour.

Loafers strike that sweet spot between comfort and style. Suede loafers gives your look a softer, more relaxed vibe while still looking polished. Whether you’re going for a classic loafer or a laid-back slip-on, these shoes are a great way to add some texture without sacrificing style. At Batch we rinse the loafer look. A casual suit, plain tee and loafers is a classic smart-casual look that works every time. We sell GH Bass Penny loafers in our shop for a reason! 

Chelsea and desert boots are perfect if you want to add a bit of ruggedness to your casual suit. They bring a cool, laid-back edge while still keeping things refined. Chelsea boots are sleek and minimal, while desert boots add a bit more texture and personality. Both give your outfit a twist without being too loud. Our honest opinion - chelsea boots are for dads and rugby lads. If you’re looking for cool boots, checkout Fracap & Danner.

Stay away from overly formal shoes like oxfords or patent leather – they’ll clash with the relaxed vibe you’re going for. These types of shoes are too stiff and structured for a casual suit and will make your look feel more "boardroom" than casual cool.

 

Accessorizing for a Casual Finish

Losing the tie is all about confidence and the right vibe. A well-fitted shirt with an open collar gives you that effortless, relaxed look. To pull it off, make sure the shirt’s collar is crisp, and if you're feeling extra chill, you can even leave a couple of buttons undone. Don’t underestimate a good tie though, they’ve become a lot less formal recently. 

 

When it comes to belts, it’s about balance. A casual leather belt is your go-to for versatility – it’s simple and works with almost anything. If you want a more relaxed look, woven fabric belts are a great choice. They add a bit of texture and are perfect for when you're going for that easygoing, summer-ready look. Again, if you want our two pence, keep it simple with plain leather. 

Hats, scarves, and sunglasses are the perfect way to add a personal touch to your casual suit. Hats give you that cool, streetwear edge, while scarves add a touch of swagger without being too formal. And sunglasses? Always a good idea. Sunglasses are, and will always be, the ultimate accessory. 

A smart casual bag is the cherry on top of any relaxed suit look. A tote bag is roomy and practical, leather backpacks give off a stylish edge, and satchels are timeless. Choose something that adds to your overall vibe without overdoing it – the key is keeping it functional and chic. 

Batch hot tip: simple tee paired with a necklace as per below.

 

Common Mistakes to Avoid When Dressing Down a Suit

Overdoing the Casual Elements

It’s all about striking the right balance. Sure, you want to look relaxed, but avoid going overboard with overly casual pieces. A hoodie, for example, might be too much. Stick to simple, clean items like a fine-knit sweater or a basic tee – they’ll keep the suit looking intentional, not sloppy.

Even when dressing down, fit is key. An ill-fitting suit – even with casual elements – will never look good. Make sure your jacket’s the right length, your trousers hit the right spot, and everything fits comfortably. The idea is to look relaxed, not like you’re wearing something too big or too small.

 

Wearing the Wrong Type of Suit

Not all suits are made for the casual look. Business suits, with their stiff structure and heavy fabric, can look out of place when you try to dress them down. Instead, go for a suit that’s designed with casual styling in mind – softer fabrics, a more relaxed cut, and less formality in the design.

Watch out for suits with too much sheen, rigid structure, or stiff lapels – these are signs that the suit was made for more formal occasions. If it feels too formal or restrictive, it’s probably not the one you want for dressing down. A casual suit should feel easy and comfortable, not stuffy.

Ignoring Seasonal Considerations

Fabric choice is key when dressing down a suit. For the warmer months, go for lighter fabrics like linen or cotton – they’ll keep you cool while still looking sharp. When the weather turns colder, heavier textures like wool or tweed will keep you warm and give your suit some added depth.

Layering is important, but make sure your layers match the season. In summer, you can get away with lighter layers like a t-shirt or a thin sweater, while in winter, you’ll need thicker layers like a chunky knit or a wool turtleneck. Always keep the weather in mind to ensure you’re both comfortable and stylish.
