Women's underwear should feel comfortable throughout the day, remain as discreet as possible under clothing and suit your personal style. At the same time, cut, material and care requirements can vary considerably. A low price or a well-known logo alone therefore says little about whether a style is suitable for its intended purpose.
The labels XS to XXL are not identical across every brand. Some manufacturers use EU sizes, while others also include UK or US sizes. If you order based only on your usual letter size, you risk pressure marks, slipping or a fit that is too loose. This is particularly important with underwear, as returns are often excluded for hygiene reasons.
Women's lace underwear may be stretchy thanks to polyamide and elastane content, but it often requires gentle treatment. High temperatures, fabric softener and tumble drying can put greater strain on lace and elastane. An attractive appearance therefore does not automatically mean low-maintenance care.
Seamless styles may be less visible under close-fitting clothing. With women's shapewear bodysuits, body measurements, stretch and the desired level of support are also important. Shaping underwear that is too tight can become uncomfortable when sitting; if you fall between sizes, follow the manufacturer's recommendation for the specific item. Shaping clothing changes your silhouette under your clothes, but it does not replace checking your individual size.
Cotton can feel different in everyday wear from polyamide or nylon. Elastane provides stretch, but is more sensitive to care than pure natural fibres. Check:
According to the product details, the Calvin Klein 3-pack of thongs contains 95% cotton and 5% elastane. It should be washed on a gentle cycle at 30 °C. Other styles containing lace or shapewear fabric may require hand washing and flat drying.
Before buying, compare your waist, hip and – for bodysuits – breast or body length measurements with the size chart for the specific item. A multipack is only economical if the size is a reliable fit. Also look for:

The lifespan of women's underwear depends on the material, how often it is worn and your washing routine. To help garments retain their shape for longer:
If you notice visible loss of elasticity, damaged seams, permanently misshapen waistbands or fabric wear, the item should be replaced regardless of when it was bought. It is not possible to give a reliable fixed lifespan for every style.
Women's thongs and seamless styles may be less visible under close-fitting trousers or dresses. However, colour, fabric thickness and the finish of the leg and waistband edges are also important. With black underwear, consider the colour of your outer garment, as it may show through light-coloured fabrics.
Measure your waist and hips, then compare the measurements with the size chart for the product in question. Brands such as Calvin Klein underwear and Tommy Hilfiger underwear may use different charts and size labels. For bodysuits, your bust measurement, body length and the position of the crotch fastening are also relevant.
A multipack can reduce the price per item and makes it easier to stock up for everyday wear. However, the saving is only worthwhile if the cut, size and care requirements are genuinely suitable. With a set containing different colours or cuts, you should also check that you will wear all the pieces regularly.
