Pour la Frime (Japan brand) mini skirt, size S, mustard

Purchased this cute pour la frime mini skirt from a boutique in Tokyo. It is lined with a side zipper and in excellent condition. It comes with a separate belt that can also be used with other skirts! It is a mustard/gold colour which would go nicely with a black turtle neck and tights. Although the tag indicates size M (Japan sizing), it is more of a size S in North American standards. Unfortunately I can't read Japanese so I'm unable to provide what the material is made of, but it seems to be a polyester blend.
