I bought this in New York. It's a popular item, and this was the last one. The size is 32, which should fit someone who wears XS to S. I've worn it about twice, and it's in good condition. The inside has a thick elastic band. Please refer to the photos. The fabric is a bit thick, so it's perfect for the beginning of autumn. It looks great with long skirts or culottes, and you can also wear it on its own for a cool look. The zipper opens into a slit. The zipper around the waist is decorative. I'll upload the size and material details later. It looks white in the photos, but the color is a beautiful black.
