Is it bad for your chest to wear cotton underwear too hot in summer-

Have shortcomings. Cotton underwear can clog the pores of breasts and nipples, just like a sponge covers our nose and mouth. How can you stand it? It's just that our breasts can't talk or express. Nipples will turn black when worn for a long time, and areola will become bigger and black. Therefore, please choose healthy underwear. Feili underwear is nice. At present, the only 3D upright cotton in the domestic market will never change shape and color, and will not produce harmful substances. It's really healthy underwear.
