Choosing men’s shirts and T-shirts: how to find the right fit, fabric and style

Choosing a new shirt sounds simple until you have to decide between a men’s shirt, a basic men’s T-shirt, a sports shirt or a roomy outdoor style. Marketing copy often focuses on appearance, while the practical details determine whether a garment feels comfortable and gets worn regularly.

Pay particular attention to these three common pitfalls:

• The wrong fit: slim fit can look smart, but too little room around the chest, shoulders or stomach makes movement uncomfortable.
• Unclear fabric composition: “soft” or “breathable” does not tell you much without percentages and care instructions.
• A colour that is less versatile than expected: black men’s shirts are easy to style, but a very dark colour may need special washing care to stay looking its best.

Below, you’ll find a practical guide to men’s shirts and T-shirts for everyday wear, work, smart-casual occasions, sport and outdoor activities.

Check the fit, fabric and size first

1. Fit: slim fit, regular fit or relaxed fit?

The fit should suit both how you plan to wear the garment and your body shape.

• Slim fit: sits closer to the body and works well for a smart office or evening look. A slim-fit men’s shirt, such as a Calvin Klein style, works best when there is enough room across the chest, shoulders and neck.
• Regular fit: offers a more traditional balance between comfort and appearance. This is often a practical choice for everyday wear and light sporting activities.
• Relaxed fit: provides extra room around the body and arms. This can be comfortable for layering, travelling or casual men’s clothing.

Don’t just look at XS to XXL on the label. Sizes vary between brands and styles. Where possible, check your chest, waist and sleeve measurements, as well as the neck size if applicable. For shirts with a size such as 39, 40, 41 or 43, the number often refers to the collar size rather than a general clothing size.

2. Fabric: choose according to how you’ll use it

A men’s cotton T-shirt is a sensible choice for everyday wear. The selection includes styles made from 100% cotton, including the Calvin Klein Smooth Cotton T-Shirt and various The North Face styles. Cotton generally feels familiar and comfortable, but always check the washing instructions and drying method.

If you want extra freedom of movement, a men’s stretch shirt could be worth considering. The Calvin Klein Poplin Stretch Slim Shirt lists a composition of cotton and elastane. Exact percentages may vary between versions, so check the product page before buying.

For sport, a cotton blend can sometimes be more practical. The Under Armour Sportstyle T-shirt lists 60% cotton and 40% polyester, with a regular fit and drying technology according to the product description. Brand claims about performance should be treated as the brand’s product information; they do not guarantee the same experience for every user.

3. Care and colour retention

If a shirt only stays looking good with complicated care, it may not suit your routine. Check:

• maximum washing temperature;
• whether it can go in the tumble dryer;
• ironing temperature;
• whether it should be washed with similar colours;
• advice on washing it inside out.

Many styles in this selection can be washed at 30 or 40 °C, but several product descriptions advise against tumble drying. Always follow the care label in the garment. This helps prevent shrinkage, misshaping and unnecessary wear.

Frequently asked questions about men’s shirts and T-shirts

Which men’s shirt size is right for me?

Measure your chest at the fullest point and compare it with the size chart for the specific brand. For shirts, also check the collar size and sleeve length. Sizes XS to XXL are not fully standardised. Tommy Jeans, for example, lists a chest range for each size, while Calvin Klein shirts are also offered in collar sizes such as 39, 40 or 43.

How long does a cotton T-shirt last?

Its lifespan depends on the fabric, how often you wear it, friction and washing. Wash it according to the care label, avoid unnecessarily high temperatures and only use the tumble dryer when permitted. A 100% cotton T-shirt can be comfortable for everyday wear, but its fit may change if it is washed or dried incorrectly.

How much does a good men’s shirt cost?

The price is influenced by factors including the brand, material, finishing, fit and availability. So don’t compare the price alone; also consider the fabric composition, size options, care costs and the number of occasions on which you can wear the shirt. A basic black T-shirt, a stretch shirt and a technical sports shirt serve different purposes and therefore cannot be compared like for like.
