15 Knit Shirt Outfit Ideas for Men

A plain T-shirt is easy, but it can look flat. A knit shirt gives you texture and shape without any extra effort. It sits somewhere between a tee and a button-up, so you get a smarter look without a stiff collar.

These 15 knit shirt outfit ideas for men cover open-knit camp shirts, polos, a knit tee and a few sweaters. Each look shows the pieces, where to wear it and a simple swap. Some are made for hot days, and some for cold ones.

1. Cream Open-Knit Camp Shirt With Black Stripes and Black Trousers

An open knit shirt looks like a summer shirt but feels like a texture piece. The black stripes run straight down, which makes you look a little taller, and the cream keeps it light. Black trousers hold it all together.

Wear it to: warm evenings out, a dinner on a terrace, a summer date.

Swap: if the open weave feels too see-through, wear a plain white tee under it.

2. Peach Waffle-Knit Polo With a Black Collar and Dark Trousers

Waffle knit has a raised grid that catches light, so a plain polo suddenly looks like it has some thought behind it. The black collar and sleeve stripes frame the peach and keep it from looking too soft. A black crochet bucket hat takes the look into streetwear.

Wear it to: a casual lunch, a gallery, a walk through town.

Swap: leave the hat at home and the same polo works for the office on a casual Friday.

3. Rust Knit Button Shirt With Cream Trousers

Rust is the easiest warm color to wear, and in a knit it looks rich instead of loud. The textured weave gives you pattern without a print. Cream trousers make the rust glow, so you don't need anything else.

Wear it to: a summer wedding as a guest, a rooftop bar, vacation dinners.

Swap: navy trousers are easier to keep clean and still look good with rust.

4. Grey-Beige Knit Polo With Black Wide-Leg Trousers

The polo has soft vertical blocks of grey and beige and a collar that sits open, which feels more relaxed than a buttoned one. Black wide-leg trousers balance the pale top. The small leather duffle finishes it, so you look like you're heading somewhere.

Wear it to: a city day, a coffee meeting, travel days in warm weather.

Swap: pleated black trousers look just as good and are easier to find.

5. White Crochet Open Shirt Over a Dark Tank

A crochet shirt worn open over a dark tank is a layering trick: the dark shows through the holes and gives the white some depth. Wide black trousers and clean white sneakers keep the rest simple. Only the shirt does the talking.

Wear it to: beach towns, festivals, a night out in summer.

Swap: button it one or two buttons if open feels too bold.

6. Tan Ribbed Knit Polo Sweater

A ribbed polo sweater gives you the look of a collared shirt and a jumper in one piece. The tan color is warm and goes with almost everything. Ribbing hugs the arms without being tight, so it suits slim and broad builds alike.

Wear it to: the office, autumn dates, a long lunch.

Swap: a charcoal version works with grey trousers when you want something less warm.

7. Cream Knit Camp Shirt With Beige Chinos and Grey High-Tops

This is the full outfit in one frame. A cream camp shirt with thin brown stripes sits over beige chinos in nearly the same tone, so the look is calm and clean. Light grey canvas high-tops keep it casual. Tone-on-tone is hard to get wrong.

Wear it to: weekend walks, brunch, a casual day at the office.

Swap: try olive chinos instead of beige for more contrast.

8. Cream Cable-Knit Sweater With Black Wide Trousers and White Sneakers

A cream cable-knit is the classic cold weather knit. Here it's cut slightly boxy, and the black wide trousers make the shape look deliberate. White sneakers lighten the bottom half so the outfit doesn't feel heavy.

Wear it to: a winter day in town, a casual dinner, travel.

Swap: put a white collared shirt under the sweater to make it a smart outfit.

9. Beige Knit Polo With a Textured Panel and Olive Tones

Soft beige looks good against olive, and this photo shows it well. The chest panel has a raised stitch pattern that adds detail without adding color. It's a quiet piece, and quiet looks tend to age well.

Wear it to: a smart casual dinner, a gallery, a weekend away.

Swap: a dark brown version looks richer on cold days.

10. Pale Blue Zip Polo With Navy Trousers

A zip polo is cleaner than a button one because there's nothing to line up. The pale blue stripes run down the front and stay quiet. Navy trousers and navy sneakers keep the color story tight.

Wear it to: a summer lunch, a garden party, a relaxed office day.

Swap: white chinos make it brighter and work well on hot days.

11. Taupe Knit Bowling Polo With Light Pink Chinos

A knit polo with white stripes down the front has a retro bowling-shirt feel. Light pink chinos sound bold, but a muted pink behaves like a neutral. White sneakers keep the bottom of the outfit bright.

Wear it to: a rooftop party, a summer date, a day at the market.

Swap: stone or cream chinos give you the same look in a plainer color.

12. Blue Shawl-Collar Cardigan Over a Light Blue Shirt

Here the knit is a layer, not the main piece. A chunky shawl-collar cardigan goes over a light blue shirt, and the two blues stay in the same family. The black belt and grey trousers keep it neat enough for work.

Wear it to: the office, a business lunch, a cool day when a jacket is too much.

Swap: a navy cardigan over a white shirt is the smartest version of the same idea.

13. Teal Ribbed Knit Tee With Black Trousers

A knit tee is a T-shirt that looks more finished. The ribbing gives it texture, and the deep teal gives it color. It fits close but doesn't cling, and that's what makes it look smart.

Wear it to: daily wear, a casual date, a night out.

Swap: dark denim works if you don't have black trousers.

14. Cream Cable-Knit Polo With Grey Textured Trousers

A cream polo with a subtle cable panel is the smartest short sleeve knit here. It's tucked into grey trousers and finished with a thin brown belt. The tuck is what turns a polo into an outfit.

Wear it to: smart casual events, a dinner with family, a job interview with a relaxed dress code.

Swap: charcoal trousers give it more contrast.

15. Olive Waffle-Knit Quarter-Zip Sweater

A quarter-zip is the easiest knit to dress up or down. Olive in a thick waffle knit looks rich on its own. The zip means no collar to fix, and you can open it to show a shirt underneath.

Wear it to: cold days, the office, a weekend in the country.

Swap: wear a white shirt collar underneath for a smarter version.

How to Pick a Knit Shirt That Works

Look at the knit, not just the color. Open knits and crochet are thin and breathable, so they suit hot days. Ribbed and waffle knits are thicker and hold their shape. Cable knits are the warmest and the most classic.

Fit decides everything. The shoulder seam should sit on your shoulder bone. The body should skim your chest and stomach, not cling to them. A knit that's too tight shows every line, and one that's too loose looks like a sack. Sleeves on a short sleeve knit should stop halfway down your upper arm.

Match the knit to the season.

Season	Knit to grab
Hot summer	Open-knit camp shirt, crochet shirt, thin knit tee
Warm spring and early fall	Knit polo, zip polo, button-up knit polo
Cool days	Ribbed polo sweater, cardigan
Cold days	Cable-knit crew neck, quarter-zip, waffle knit

Pick colors that go with what you own. Cream, tan, navy and olive pair with most trousers. Add one color like rust, teal or blue to start. For more ideas, see our guides to old money knitwear outfits and street style sweater outfits.

Tuck or untuck? A knit polo looks sharpest tucked into trousers with a belt. Camp shirts and knit tees are meant to hang loose. If you want to tuck, our guide on how to tuck in a shirt shows the full and half tuck.

Wash them gently. Knits stretch on a hanger and shrink in a hot dryer. Wash cold, lay flat to dry, and fold them instead of hanging them. Need a smarter option for work? Try our formal sweater outfits.

FAQ

What is a knit shirt? A knit shirt is a shirt made from knitted yarn instead of woven cloth. That includes knit polos, open-knit camp shirts and knit tees. It stretches a little and has a visible texture.

Can I wear a knit shirt to the office? Yes. A fine knit polo or a ribbed polo sweater is fine in a smart casual office. Choose a solid color, tuck it in and wear it with a belt.

How should a knit shirt fit? Close to the body but not tight. You should be able to pinch a little fabric at the waist, and the shoulder seam should sit on the shoulder bone.

What goes with a knit polo? Chinos, tailored trousers, dark jeans and white leather sneakers all work. Keep the trousers a solid color so the knit is the focus.
