Choosing men's shirts and polos: practical buying tips for every occasion

A good shirt should look more than just attractive in the product photo. It should also suit your build, feel comfortable throughout a long working day and keep its shape after multiple washes. When looking for men's shirts and polos, you will come across terms such as slim fit, premium cotton, easy care and stretch. These terms only tell you something useful when you understand the product specifications behind them.

The most common buying mistakes are:

  • Choosing a fit without checking the size chart. A men's slim fit shirt may fit closely in one collection and more loosely in another.
  • Assuming cotton automatically means comfort. The type of fabric, the weave and the percentage of elastane all affect how a shirt feels.
  • Looking only at colour and brand. A men's black polo or dark blue men's shirt is easy to combine with other clothes, but the collar, fastening and fabric determine whether the garment is suitable for work or everyday wear.

What should you look for in men's shirts and polos?

1. Fit: slim fit, regular fit or longer styles

A slim fit sits closer to the body around the chest, waist and arms. This works well for a polished smart-casual outfit, but may feel less comfortable if you move around a lot or prefer more room around the stomach. So do not just check the letter size. Also look at the chest, waist and sleeve measurements in the product information.

A regular fit generally provides more freedom of movement. For example, the Tommy Hilfiger 1985 Regular Polo uses a regular fit, making it practical with jeans, chinos and shorts. A tall model can be a good solution for taller men. The Urban Classics Tall Tee is made from 100% cotton with a weight of 180 gsm and is designed as a longer T-shirt style.

Also pay attention to the collar size when choosing a men's shirt. Sizes such as 39, 40 or 43 often refer to the collar measurement in centimetres, rather than the same sizing system as XS to XXL.

2. Material and stretch

A men's cotton shirt usually feels lightweight and familiar. Piqué has a distinctive texture and is often used for polos. Poplin is smoother and looks more formal, while twill has a slightly sturdier weave.

Stretch means that elastane or a similar flexible fibre has been added. According to the product information, the Calvin Klein Stretch Pique Slim Button Polo consists of 96% cotton and 4% elastane. This can provide extra freedom of movement with a close-fitting style. With a men's stretch shirt, it is also worth checking the percentage of cotton: two stretch shirts can feel quite different.

Brands may promote features such as breathability, shape retention or durability. Treat these as the brand's product information, rather than a guaranteed result. According to Calvin Klein's own information, the cotton used in certain models is certified organic cotton. Always check the composition and certification information on the product page and care label.

3. Colour, collar and occasion

Neutral colours are practical:

  • Black: suitable for a minimalist casual outfit or evening look.
  • Dark blue: easy to combine with beige, grey, denim and white.
  • White: useful as a base layer or under a blazer.
  • Lavender Lustre: adds a striking splash of colour to a classic outfit.

A polo with a ribbed collar and button fastening sits somewhere between a T-shirt and a shirt. A Kent collar on a shirt looks more formal. So think about how you will wear it beforehand: at home every day, in the office, while travelling, for dinner or for a smart-casual occasion.

Frequently asked questions about men's shirts and polos

Which men's shirt size should I choose?

Measure a shirt that fits well across the chest, shoulders and sleeves, then compare those measurements with the brand's size chart. With shirts, pay particular attention to the collar size. A men's slim fit shirt can feel smaller than a regular fit in the same letter size.

What is the difference between a men's polo and a T-shirt?

A men's polo usually has a collar and a short button fastening. This gives it a slightly smarter appearance than a men's T-shirt. A round-neck or V-neck T-shirt is generally simpler and suitable as a base layer or casual top.

How can I keep cotton shirts looking good for longer?

Follow the care label, wash dark colours with similar colours where possible and do not use bleach unless permitted. Hang shirts up straight after washing. The product information may state that a shirt is machine washable, but drying instructions vary by model: some shirts must not be tumble dried.
