T-shirts are the most worn pieces in most wardrobes. Two styles cover most needs: the polo and the crew-neck tee. Knowing when to wear each, and how they should fit, makes everyday outfits look sharper.

Polo T-shirts

A polo has a soft collar and a short button or zip placket. It looks neater than a regular tee and works for casual offices, golf, lunches and travel.

How to wear it: with chinos and loafers for smart casual, or with jeans and sneakers for weekends. Polos can be tucked in with chinos for a neater look.

Zip and knit polos

Knitted polos with a zip placket feel more refined and have a retro feel.

Polo collars with modern cuts

Drop-shoulder polos and long-sleeve polos with typography give the classic polo a modern twist.

Crew-neck T-shirts

A crew-neck tee has a round neckline and no collar. It is the most basic and versatile T-shirt.

How to wear it: on its own with jeans, or as a base layer under shirts, jackets and blazers.

Colour-block tees

Colour-block tees use contrasting panels for a sporty, playful look.

Polo or crew neck: quick guide

  • Casual office: polo.
  • Lunch or golf: polo.
  • Under a jacket or blazer: crew neck.
  • Gym and sport: crew neck in performance fabric.
  • Weekend: either.

Fabrics

  • Cotton: soft and breathable; the everyday choice.
  • Piqué cotton: textured weave used in classic polos; breathable and structured.
  • Polyester and blends: quick-dry and good for sport.
  • Knits: dressier polos for evenings.

Fit tips

  • Shoulders: seam at your shoulder edge (unless it’s a drop-shoulder style).
  • Sleeves: end around mid-bicep and sit close to the arm.
  • Length: the hem should cover your belt and end around mid-zip.
  • Chest: fitted but not tight.

Plus-size tips

  • Choose regular fits in thicker cotton that skims rather than clings.
  • Darker colours and vertical details like a placket create a longer line.
  • Crew necks should not be too tight around the neck.

Outfit ideas

  1. Smart casual: black polo, beige chinos, brown loafers.
  2. Weekend: colour-block tee, light jeans, white sneakers.
  3. Dinner: navy knit polo, grey trousers, suede loafers.
  4. Layered: white crew-neck tee, denim shirt open on top, black jeans.

Care tips

  • Wash tees and polos inside out in cold water.
  • Lay knit polos flat to dry so they don’t stretch.
  • Don’t hang heavy cotton tees for long; fold them to keep the shoulders in shape.

Common mistakes to avoid

  • Popping polo collars. It looks dated.
  • Buttoning all polo buttons with no tie. Leave the top one open.
  • Faded, stretched tees for going out. Keep them for home.

Frequently asked questions

Is a polo smart enough for the office?

In business-casual offices, yes, especially in solid dark colours tucked into chinos.

Should polos be tucked in?

Tuck them in with chinos for a neat look; leave them out with jeans.

What is the difference between a polo and a rugby shirt?

Rugby shirts are heavier, usually long-sleeved, with a sturdier collar and often bold stripes.

How many T-shirts should I own?

Around six to eight: a mix of plain crew necks in white, black and grey, plus two or three polos.

Choosing colours for a T-shirt collection

Start with neutral tees in white, black, grey and navy. These go with every pair of jeans and chinos. Then add two or three polos in classic colours like navy, black, white or olive. Finally, add one or two colour-block or printed tees for weekends.

Buying checklist

  • Hold the fabric up to the light; good tees are not see-through.
  • Check that side seams are straight and do not twist.
  • Look at the collar on polos: it should lie flat and keep its shape.
  • Choose 100% cotton or cotton-rich blends for everyday comfort.

A week of T-shirt outfits

On Monday, tuck a black polo into beige chinos for a business-casual office. On Tuesday, wear a navy knit polo with grey trousers for a client lunch. Midweek, switch to a white crew-neck tee under an open denim shirt. On Friday, choose a colour-block tee with light jeans and sneakers to start the weekend early.

One more tip

Replace your most-worn tees once a year. White and light tees yellow at the collar and underarms over time, and a fresh set of basics instantly makes everyday outfits look sharper.

In short: polos look polished and suit casual offices and lunches, while crew-neck tees are the ultimate everyday base layer. Get the fit right at the shoulders and sleeves, and both will make your outfits look effortless.
