100% cotton, with an elastic waistband and drawstring for easy adjustment ☺︎ The fabric is neither too thin nor too thick, and will be perfect for the coming season! It's a men's size S, so it's also cute on women! My child wore it a few times and outgrew it. As shown in the third photo, there is a name written on it, which I will erase before shipping. Thank you for your understanding and purchase. Thank you for looking.
