What underwear is the healthiest to wear?

Healthy underwear should be those that are comfortable to wear and can bring good massage to our breasts. For daily wear, it is recommended to choose comfortable fabrics and underwear that conform to ergonomics. What needs special attention is to choose underwear with good air permeability in summer or in daily life. At present, the big brands in the world use sponges or upright cotton, which are particularly breathable materials.
