Plain Casual Shirts for Men: How to Make a Simple Shirt Look Sharp

Confession first. For the longest time my cupboard was basically a printed-shirt museum. Palm trees, tiny anchors, a flamingo one (don't ask). And every single morning, without fail, I'd push past all of them and pull out one of two plain casual shirts. An old light blue oxford, or a white one that had gone soft from about a hundred washes.
Took me years to see what was going on. Those two shirts were doing the actual work. Everything else was just hanging there looking busy.
So no, I don't think plain shirts are boring. A plain shirt looks boring when the fabric's flat, the collar's wrong for the occasion, or it fits like a borrowed one. Get those three right and it's the most useful thing you own.
Why Plain Shirts Beat Prints for Everyday Wear
Prints get remembered. That's lovely the first time and a bit awkward the third. Wear the flamingo one to two dinners with the same friends and somebody will say something.
Wear a navy shirt twice a week for a month though, and nobody clocks it. It just looks right, every time.
Plain shirts also don't date. My navy one is years old and still looks perfectly normal. The anchors, on the other hand, are now a gym shirt at best.
I've kept a couple of prints, for holidays and the odd party.
Choose the Right Fabric: Oxford, Poplin, Linen or Brushed Cotton
When there's no pattern, people look at the cloth. Obvious, but it took me years.
Oxford is my favourite. It's got a soft, slightly nubbly weave, so even plain white has a bit of life to it when you're up close. Poplin is smoother and crisper. Think of it as a formal shirt on its day off. Then linen, and linen blend shirts, which have that slightly uneven texture and loose drape that just works in summer. For winter there's brushed cotton, which feels almost like suede and makes a plain shirt look warm and a bit expensive.
These days if I've got two shirts in one colour, they're two different fabrics. Learnt that after buying three identical white poplins in one go.
Pick the Collar That Suits the Occasion
Nobody thinks about collars. I didn't either. But the collar is quietly deciding how formal you look, every time you put a shirt on.
A spread collar is the smart one, made for blazers and tucking in. Button-down collars are more relaxed and they stay neat when you leave the shirt open at the neck, so that's what I wear most weekends. Cuban collars sit flat and open, no top button at all, and honestly they only make sense on holiday or at a warm dinner somewhere outdoors.
The plain casual shirts collection has all three. Figure out where you'll mostly wear the shirt, then pick the collar.
How a Plain Shirt Should Fit
This is where plain shirts get harsh. A busy print hides a lot of sins. A solid colour hides none. Any pulling across the chest, any spare fabric puffing out at the waist, you'll see it in the mirror instantly.
In the trial room I do the same three things every time. Shoulder seam should sit right at the edge of the shoulder, not drooping down the arm. Arms down, and the cuff should hit around the wrist bone. Then arms straight up, like reaching for a bag on a top shelf. If the shirt comes untucked, it's too short to tuck, simple as that.
Regular fit is kinder in the heat. Slim fit looks cleaner under a jacket.
Five Plain Shirts, One Week of Outfits
If I had to start again from zero, I'd buy five. White, light blue, beige, navy, black.
Monday is nearly always the light blue oxford, tucked into grey tailored trousers, brown shoes. Somewhere around Wednesday the white one comes out with navy trousers, and a blazer if a client's coming in.
Fridays I loosen up. A beige shirt in a linen blend, left untucked over dark jeans with the sleeves rolled. Fine at the desk, fine at drinks after.
Saturday is the navy one worn open over a white tee, with stone chinos and sneakers. And if there's a dinner that night, a black casual shirt with charcoal trousers and the top button open.
Five shirts. A whole week. Nobody has ever said "didn't you wear that on Monday?"
Styling Tricks That Make Plain Shirts Look Better
Some tiny habits make a big difference.
Roll your sleeves properly. Fold the cuff back once, then again, so it sits just under the elbow. Not shoved up in a lump, like I did for years.
If a shirt's a little long to leave out but too casual to tuck in all the way, do a half-tuck at the front only. Looks deliberate.
T-shirt underneath? Keep it plain, white or light grey, crew-neck, and make sure it isn't peeking out of the open collar.
How to Care for Plain Casual Shirts
Solid colours show wear faster than prints do. So whites go in with whites, darks with darks, always cool water, and I turn the dark ones inside out. Everything dries on a hanger, not in the dryer, because heat slowly shrinks cotton and dulls colour. Iron while the shirt's still a little damp and it goes much quicker. Also, rotate them. A shirt worn three times a week loses its collar long before anything else.
Frequently Asked Questions About Plain Casual Shirts
Can a plain shirt look stylish?
Definitely. A plain shirt looks stylish when it fits well and the fabric has some texture, like oxford, linen or brushed cotton. Choosing the right collar for where you're going and rolling the sleeves neatly do far more for the look than any print.
What should I wear under a plain casual shirt?
A plain crew-neck T-shirt in white or light grey is the best option under a plain casual shirt, particularly a pale or thin one. Make sure it doesn't show at the collar when the top button is undone, and avoid dark or printed tees under light shirts.
What is the difference between an oxford and a poplin shirt?
Oxford has a thicker, slightly textured basket weave that looks relaxed and softens with every wash. Poplin has a tighter, smoother weave, so it feels crisp and looks a little more formal. Oxford suits weekends and casual offices, while poplin leans smarter.
How do I stop a white casual shirt from turning yellow?
Wash it with other whites in cool water, go easy on the detergent, and dry it in the shade rather than harsh sun. Always put it away clean, since old sweat marks are a big cause of yellowing, and deal with collar and underarm stains as soon as you see them.
Start With Two Plain Shirts
Five feels like too many? Start with a light blue oxford and a white shirt. Add beige, navy and black later. Explore plain casual shirts at Selected and build your wardrobe on pieces that earn their place.
