I'm selling this because I have multiple. It's a like-new item, only tried on. It's size 8-20, but it's the same as an adult S/M size, so it's not for children. It says 56, but I think the inner circumference is about 58. It has good depth, and the pony is small like in the 90s, so it's a model I personally own a lot of and like. It's reversible, but it's not a shallow type, and both sides are cotton, so it's comfortable to wear and the silhouette is very beautiful. Unisex, please consider it.
