Women's sportswear set 100% polyester The lining is mesh material, so it feels smooth. Please note that the top and bottom sizes are different ^ ^ Top...M size Length - about 66cm Width - about 52cm Bottoms...S size Inseam - about 70cm I bought it a few years ago, but I haven't had many opportunities to wear it. I've worn the bottoms 2-3 times. Thank you!
