This is a women's size M. I wore this under my uniform when I was in a cheerleading circle in my early 20s. My family was storing the ones for the members at the time, and a lot of them came out, so I'm selling them one by one. The fabric is leotard material, and it's a very sturdy underskirt, so I don't think the wear and tear is very noticeable. However, this is a used item that has been stored personally, so please purchase only if you understand this.
