As a woman, you understand the challenges in finding comfortable bras. You likely have specific styles that you prefer, and you may even have fabric preferences, such as a 100% cotton bra. Your bra’s fabric can have a significant impact on how comfortable you are. This is what you should know about different bra fabrics and how they impact your comfort.
Silk=Absorbent, Quick Drying
Silk is one of the most expensive fabrics used in bras, but it feels soft, silky and smooth against your skin. It also has good breathability, and it dries quickly after it gets wet. However, silk requires specialized care. For example, you need to hand wash and air dry these undergarments. Although these bras are comfortable and beautiful, they are not durable.
Polyester=Strong & Easy To Care for
Polyester is a synthetic fabric like Lycra, rayon, elastane, modal, Dacron, polyamides, viscose and others. These fabrics tend to have added stretch and strength. Polyester is common in sports bras as well as everyday bras with and without wires.
Manufacturers use polyester to create low-stretch knits. Polyester fabrics provide superior support due to their stretch. They do not pill, and they keep their shape. This material is also highly durable, absorbent and breathable. Because polyester is a synthetic material, manufacturers make it from chemicals, which can irritate the skin.

Cotton=Soft, Durable, Breathable
Like most women, you likely have a drawer full of 100 cotton underwear women. You understand how comfortable they are and likely wear them nearly every day. Cotton is a common undergarment fabric because it feels soft against your skin. As a natural fiber, it is also warm and breathable. It absorbs moisture as well.
However, cotton is not as durable as other fabrics. In addition, it can shrink, especially at first. Finally, cotton can become deformed if it does not receive proper care.
Wool=Durable, Moisture Wicking
It may surprise you to learn that some bras have wool fabric. Wool is quite popular. Many bras have wool blends because the wool adds stretch and increases durability. This type of wool fabric does not cause you to itch and is not coarse or chunky.
It tends to feel soft. Wool blends also breathe well and normalize your body temperature. They also don’t have an odor when they absorb sweat. Wool bras are high-priced, so they are not as common.
How Comfortable Bras Fit
You need a bra that has a snug band that doesn’t dig into your skin or gap. Your cup size should fit your breasts perfectly without gapping or allowing your breasts to spill out. Also, make sure your breasts do not slip out beneath your bra. The center of your bra should lay flat against your breastbone.
The straps should hold the bra on, but they should not droop, sag or dig into your shoulders. If you choose an underwire bra, make sure that the wires curve naturally under your breasts and do not poke, pinch or bend.
As you determine the bra fabric you prefer, test bra styles, such as the 360 bra, and find those that fit you best and make you feel great.
