This skirt is 100% polyester, but it has a moist, glossy feel and is very elegant. I think it's a piece that can be worn both casually and formally. I bought it thinking of wearing it for special occasions, but it's still unused, so it's in beautiful condition♡. I've kept it covered, but please understand that it's been stored at home. I might delete this listing if I end up using it. (^^)
