Ice silk fabrics are actually polyester and spandex. Nylon, just that polyester is worthless and not high-grade. A nice name is ice silk. If you don't believe me, just look at the fabric composition and you will know that I am right. If you wear it, you can wear it as long as it is not a special constitution. For example, you can only wear pure cotton, and other constitutions are allergic. Ice silk does not stick to the body, and now many pajamas use this fabric. But there is one disadvantage: it is hot when it is hot and cool when it is cold.

But inappropriate underwear can not only show your figure, but also make your chest smaller and droopy.
