I purchased this at a store about two years ago. I'm selling it to organize my shelves. It has a zipper in the back and a suede-like fabric. It has two pockets. The waist is about 26 centimeters. It's elasticated from there, so it stretches a bit. I think the waist of this item is not a slim fit. I myself have a wave-type body shape and a small waist, usually wearing S or XS sizes. However, it was a little loose when I wore a thin knit top and tucked it into the skirt, so I think it might be a good size for someone who usually wears a size M (^^) If you wear a thick knit top and tuck it into the skirt, it seems like it would fit someone who usually wears a size S just right＊ For your reference...＊
