This is a Sheglit dress. I purchased it here, but I'm selling it to organize my wardrobe. The size is [M]. The waist is elastic. The skirt has multiple layers, so it has some volume, but I think it would be cute to add even more volume with a petticoat (*´｀) I don't see any noticeable damage, but since it's a used item, please refrain from purchasing if you are sensitive to such things.
