Choosing women’s and men’s underwear: practical tips for comfort, fit and everyday wear

Buying underwear may seem straightforward, but an attractive product photo says little about how it will fit after a long day. With women’s and men’s underwear, three common pitfalls are particularly likely to lead to a disappointing purchase: choosing the wrong size, selecting materials that do not suit the intended use, and opting for designs that turn out to be visible or uncomfortable beneath clothing.

With women’s shapewear, the level of control also plays a role. High-waisted shaping briefs that are too tight may be less comfortable to wear than a style offering light support. When choosing men’s underwear, the focus is often on freedom of movement, an elasticated waistband and a fabric suitable for everyday wear. By comparing the right specifications, you can make a more informed choice and avoid relying solely on brand names or marketing terms.

Three common underwear pitfalls

1. Relying solely on the size letter

A size M is not the same in every style. The fit is influenced by the cut, the amount of elastane and the rise. Always check the size guide for the specific product. For larger sizes, the combination of waist and hip measurements is particularly important.

A size that is too small can cause rolling edges with shapewear. A size that is too large may not fit closely enough and could show beneath a dress. With boxer shorts, the wrong size can cause them to ride up or provide insufficient support while moving.

2. Confusing “seamless” with completely invisible

Seamless shapewear usually has fewer visible seams, but the leg opening, waistband and fabric thickness also determine how the garment sits beneath an outfit. A low back, for example, calls for a style with a suitable back design. Also check that the colour works with the clothing you plan to wear over it.

3. Choosing firm control for everyday wear

More compression is not automatically more practical. For everyday wear, light shaping may be the more sensible choice, while a firmer style may be better suited to a particular outfit or occasion. Pay attention to the product description and distinguish between visual shaping and medical effects. Shapewear is a garment and is not a substitute for a medical device.

Important specifications to compare

Material: cotton, modal, nylon and elastane

For men, cotton boxer shorts with elastane are a practical choice if you are looking for a familiar, stretchy fabric. According to the product descriptions of several Urban Classics styles, a composition of 95% cotton and 5% elastane provides stretch and freedom of movement.

Modal generally feels lightweight and soft. The Urban Classics modal style consists of 52% modal, 44% cotton and 4% elastane. The product description also states a weight of 180 g/m² and properties such as breathability and moisture wicking. These are product specifications; the experience may vary from person to person.

Women’s shapewear often contains nylon and spandex. The Feelingirl style has an outer layer made from 62% nylon and 38% spandex and an inner layer made from 44% nylon and 56% spandex. The construction includes mesh and bonded seams. As details like these can affect the product’s lifespan, it is important to follow the care instructions.

Fit and rise

When choosing shaping shorts for women, consider:

  • Rise: a mid-rise or high-rise style fits differently from a low-rise model.
  • Back design: a low back may be suitable for dresses with a low back.
  • Leg length: mid-thigh styles cover part of the upper leg and may help reduce friction between the thighs, without making a health claim.
  • Edges: according to the product description, anti-slip material or reinforcement may help keep the legs in place more effectively.
  • Underwires or boning: the Feelingirl style has internal stainless-steel boning at the sides; check whether this feels comfortable during prolonged wear.

Care and expected lifespan

How long a garment lasts depends on how often it is worn, washing, drying and the amount of tension placed on the fabric. Shapewear with bonded seams requires extra care. The aforementioned Feelingirl style should be hand washed; machine washing, tumble drying and dry cleaning are not recommended.

According to the product description, FILA boxer shorts can be machine washed in cold water. Urban Classics also recommends machine washing with similar colours, using a low drying temperature or air drying. Always check the care label, even when the general product information lists other options.

Frequently asked questions about women’s and men’s underwear

How do I choose the right underwear size?

Measure your waist and hips at the points indicated in the size guide. Compare these measurements with the product page rather than relying only on S, M, L or XL. With shapewear, it is generally better to follow the size guide than to choose a smaller size for extra control.

How long does underwear typically last?

This depends on how often it is worn, the number of washes, the fabric and how it is cared for. Elastic fibres lose their stretch over time. Rotating several pairs, washing them according to the care label and using low drying temperatures can help preserve the fit and elasticity for longer.

Are multipacks cheaper than individual pairs of underwear?

A 3-pack of boxer shorts or 5-pack of boxer shorts can reduce the price per pair, but always compare the total price, material composition and available sizes. A multipack is particularly practical when all the pairs have the same fit and colour that you actually want to wear.
