What is the material of a comfortable bottoming shirt you bought?

I feel comfortable with both materials, one is pure cotton and the other is pure silk.

First, the cotton bottoming shirt absorbs sweat, so the whole body won't feel bored, especially in summer, and it won't feel the discomfort of clothes sticking to the body, so it is more breathable. Some people are allergic to materials, but cotton-padded jacket is not.

Second, silk clothes are slippery to the touch, cold to the ice, and comfortable to wear in summer. Moreover, the texture of silk clothes is beautiful, classy and tasteful, especially shirts and the like. It feels beautiful with suits, coats and woolen coats.

In short, clothes made of any material are actually personal preferences. Like me, I don't like wearing cotton and linen clothes. I don't like the touch, but I like it for some people, so the comfort of clothes mainly depends on personal preference. What you like is the best.
