Underwear is the clothing item we wear the longest and closest to our bodies, yet we often choose it without much thought. Meanwhile, the material, cut, and washing method are important for the comfort and hygiene of intimate areas. In this guide, we explain why cotton is so often recommended, when other materials are suitable, and how to care for your underwear daily.
This text is general in nature and does not replace medical advice. If you experience recurrent infections, irritation, or other ailments, consult a gynecologist.
Why cotton?
Cotton is a natural plant fiber. It has several characteristics that make it well-suited for underwear:
- absorbs moisture, so the skin stays dry longer,
- is breathable, which reduces skin overheating,
- is soft and rarely irritates, even sensitive skin,
- can be washed at higher temperatures, usually 40–60°C, if the manufacturer allows it.
A warm and humid environment promotes the growth of microorganisms. Therefore, gynecologists often recommend cotton underwear, or at least underwear with a cotton gusset, especially for those prone to infections.
100% cotton or a blend?
Pure cotton is breathable but less elastic and may lose its shape after washing. Therefore, most cotton panties contain a few percent elastane, which improves fit and prevents them from slipping or digging in. Such an additive does not detract from cotton's main advantages. It is worth paying attention to the gusset: it's good if it's cotton, regardless of the material of the rest of the underwear.
You will also find modal cotton (modal is a cellulose fiber, very soft and absorbent) and organic cotton, grown without synthetic pesticides. Both are comfortable for everyday wear.
When are other materials suitable?
Lace
Lace panties look impressive and pair perfectly with a matching bra set. They are usually made of polyamide and elastane, so for sensitive skin, it's best to choose models with a cotton gusset. See lace panties.
Microfiber and seamless models
Smooth microfiber panties don't show through tight clothing, making them ideal for dresses and trousers made of thin fabrics. Seamless models have no side seams or edges that can rub. See seamless panties.
Sports underwear
For intense workouts, technical fabrics are used that quickly wick sweat away and dry quickly. After training, it's advisable to change into dry, cotton underwear.
Cut matters
The best material won't help if the underwear is ill-fitting. Too tight, they compress, chafe, and restrict airflow. Too loose, they shift and wrinkle.
- Classic and high-waisted briefs provide the most coverage and are comfortable for everyday wear. See high-waisted briefs.
- Women's shorts and boxers don't dig into the groin and are well-suited for wearing under skirts, as they reduce thigh chafing.
- Brazilian briefs are cut higher on the buttocks but have a wider back than thongs. See Brazilian briefs.
- Thongs don't show through clothing. If you're prone to irritation, it's better to wear them occasionally and choose models with a cotton gusset. See women's thongs.
You can choose your underwear size based on your hip circumference. You'll find a chart on the how to choose your size page.
How to recognize good cotton underwear
When purchasing, pay attention to a few details visible in the product description and photos:
- Composition: in cotton underwear, cotton should constitute the vast majority of the material, with elastane making up a few percent.
- Gusset: cotton, preferably double, meaning with an additional layer in the crotch.
- Elastic bands: soft, fabric-covered or flat, which do not dig into the waist and groin.
- Seams: flat, without thick lumps on the inside.
- Size: fitted to your hip circumference, not "just in case". Underwear that shifts will chafe just as much as underwear that is too tight.
Well-made cotton underwear will retain its shape after several washes, and the elastic bands will not lose their elasticity.
Daily habits that help
- Change your underwear daily and after exercise or any situation where you sweat heavily.
- Do not sit for long in a wet swimsuit or sweaty athletic wear.
- For nighttime, choose loose, breathable underwear or pajamas, e.g., from the pajamas collection.
- Use panty liners in moderation, as some of them can restrict breathability.
- For intimate hygiene, use mild products without strong fragrances.
How to wash cotton underwear
Cotton underwear can usually be machine-washed at the temperature indicated on the label, most often 40°C, and white cotton often at 60°C. Wash them separately from towels and outerwear, preferably in a laundry bag. Avoid fabric softeners, as they can reduce cotton's absorbency and irritate the skin. Wash new underwear before the first wear. Replace underwear when it loses its shape, the elastic stretches, or the fabric becomes thin. More details in the guide how to wash lingerie and bras.
Frequently Asked Questions
Is only cotton underwear "healthy"?
No, but cotton is the safest choice for everyday wear, especially for sensitive skin. Underwear made from other materials is best chosen with a cotton gusset.
How many pairs of underwear should one have?
Enough to change them daily and not have to do laundry every day. Many people have at least a dozen pairs.
Is cotton underwear suitable for tight clothing?
Classic cotton briefs may show through thin, fitted trousers or dresses. In such cases, seamless models or microfiber with a cotton gusset are better, combining a smooth look with breathability in the most important area.
Can underwear be returned?
For hygiene reasons, sealed underwear can only be returned if the packaging has not been opened. Details can be found in the frequently asked questions.
