Cotton really is one of nature's wonder fabrics. A natural fiber, cotton is hypoallergenic, which is ideal for sensitive skin. It's also breathable, which is an important benefit in maternity bras. Pregnancy can bring sudden temperature swings and discomfort, especially in warm weather. A cotton maternity bra will keep you drier and more comfortable as your body changes and grows.
Cotton knit maternity bras are soft against the skin and usually have a touch of Lycra or other synthetic to add gentle stretch to support growing breasts. But cotton can still be strong enough to support the additional 10-18 ounces of weight breasts take on during pregnancy. Some cotton maternity bras have lined cups for added support and other styles are constructed with an inner support sling. Leotard back design helps ease shoulder and back strain, as do the wider straps typically found on maternity bras. Bras aren't the only part of your maternity wardrobe available in cotton. Stretch cotton briefs and panties feel great against the skin and have the same breathable quality as cotton bras. Cotton maternity lingerie can go a long way towards your comfort as your pregnant body changes and grows.
