Choosing men's shirts and T-shirts: pay attention to fit, material and care

A good shirt should suit your everyday needs. However, choosing one is often made more difficult by attractive product photos, vague terms such as “premium cotton” and fits that vary from one brand to another. When it comes to men's shirts and T-shirts, three pitfalls are particularly important: choosing the wrong size, selecting a material that does not suit how you intend to wear it, and failing to check the care instructions in advance.

By comparing the material, fit, colour and care requirements, you can find a shirt more quickly that is suitable for work, leisure or a streetwear look.

Three common pitfalls when choosing men's shirts and T-shirts

1. Choosing a fit based on size alone

An M from one brand may fit differently from an M from another. A men's slim fit shirt sits closer to the chest and waist, while an oversized men's T-shirt offers extra room. Even within the same brand, a style may come up large or small.

So always check:

  • the size guide for the specific product;
  • the chest and waist measurements;
  • the description, such as slim fit, fitted, regular or oversized;
  • the advice provided if a style comes up large or small.

For example, the Calvin Klein Core Monologo Pocket Slim Tee is described as coming up large. According to the product information, anyone wanting a standard fit may wish to consider going down a size. The Calvin Klein Core Institutional Logo Slim Tee, on the other hand, is described as coming up small, so going up a size may be more logical for a standard fit.

2. Confusing “cotton” with 100% cotton

The term cotton does not automatically mean that a garment is made entirely from cotton. A men's cotton shirt, for example, may be a cotton blend. This can be practical if you are looking for stretch or crease resistance, but it is not the same as a 100% cotton men's T-shirt.

Pay attention to the difference between:

  • 100% cotton: according to the product information, the main fabric is made entirely from cotton;
  • cotton blend: cotton is combined with elastane or other fibres, for example;
  • organic cotton T-shirt: check whether this is stated explicitly on the product page and whether any certification is mentioned;
  • men's stretch shirt: often cotton with a small amount of elastane to allow greater freedom of movement.

The Calvin Klein Smooth Cotton T-Shirt is listed as 100% cotton. The Urban Classics Heavy Oversized Tee is also made from 100% cotton. The Calvin Klein Poplin Stretch Slim Shirt, on the other hand, is described as a cotton blend with elastane, which can give the shirt greater flexibility.

3. Interpreting easy care too broadly

An easy-care shirt is not automatically crease-free or suitable for every tumble dryer. Product descriptions may mention crease resistance or easy care, but the washing instructions on the garment label remain the deciding factor.

Check before buying:

  • the maximum washing temperature;
  • whether the shirt can be tumble-dried;
  • the recommended ironing temperature;
  • whether dark colours should be washed separately;
  • whether the garment should be hung up immediately after washing.

The Calvin Klein Twill Easy Care Slim Shirt is described as having a cotton-twill blend and being easy to care for. The product information recommends washing at 40 °C or according to the label, and hanging it up immediately to help reduce creasing. This does not mean that ironing will never be necessary.

Which product specifications are decisive?

Material and fabric weight

For everyday wear, 100% cotton, the knit structure and fabric weight are useful points to check. A T-shirt weighing 180 g/m² will generally feel different from a heavier 240 g/m² model. The Urban Classics Heavy Oversized Tee uses 240 g/m² single jersey. This is a specific detail that helps distinguish the model from lighter basics.

An organic cotton T-shirt may be appealing if you pay close attention to the fibre composition. According to the product information, the Calvin Klein Core Institutional Logo Slim Tee is made from 100% organic cotton. When considering sustainability claims, always check the available product information and any certificates; do not draw conclusions from the marketing name alone.

Fit and occasion

  • Slim fit: suitable for a smart, close-fitting outfit with jeans, chinos or a blazer.
  • Regular fit: a practical middle ground for everyday wear and layering.
  • Oversized fit: offers more room around the body and shoulders, making it suitable for casual men's clothing and streetwear.
  • Tall fit: a longer cut can be comfortable if standard T-shirts tend to come up too short.

A black men's T-shirt is easy to combine with denim, shorts, overshirts and jackets. A dark blue or charcoal style offers similar versatility, but creates a slightly softer contrast than black.

Collar, fastening and care

For a T-shirt, the neckline finish, sleeve length and fabric structure are important. A crew neck works well as a standalone basic and as a layer underneath a shirt or jacket. With a shirt, you should also check the collar, button fastening and cuffs.

A men's stretch shirt can offer greater freedom of movement thanks to a small amount of elastane. The Calvin Klein Poplin Stretch Slim Shirt is listed with a Kent collar, long sleeves, a slim fit and a composition that includes elastane. The product information states that it is machine-washable at 40 °C, should be ironed at a low temperature and must not be tumble-dried.

  1. Consider how you will wear it: for work, everyday wear, layering or streetwear.
  2. Choose your preferred fit: slim fit for a close-fitting silhouette, oversized for extra room.
  3. Check the composition: 100% cotton, a cotton blend or cotton with elastane.
  4. Compare the size guide: do not rely solely on S, M, L or a collar size.
  5. Check the care instructions: drying and ironing requirements can vary between products.
  6. Check the colour and styling options: black, dark blue, charcoal and neutral shades are practical for a versatile wardrobe.

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

How does a men's slim fit shirt fit?

A slim fit shirt generally sits closer to the chest, waist and arms than a regular fit. The exact fit varies by brand and model. So check the size guide and see whether the product comes up large or small. If you are between two sizes, your preferred way of wearing it may be the deciding factor: close-fitting or with extra room for movement.

Is a 100% cotton T-shirt suitable for everyday wear?

It can be a practical choice if you are looking for a natural fibre composition. However, the thickness, knit structure and washing instructions also influence how the shirt feels and how it should be cared for. So do not check only whether it is “100% cotton”; also look at the fabric weight, fit and drying instructions.

How can you stop a black men's T-shirt from quickly losing its appearance?

Wash dark clothing inside out with similar colours and follow the label instructions. Avoid bleach and use the recommended drying method. The Urban Classics models are listed as suitable for cold washing with similar colours and mild detergent. The instructions on the physical garment label always take precedence.
