This is a one-piece dress. I wore it once at USJ a few years ago. I washed it and stored it in the closet. There is no size label, so I think it's free size. Please check the measurement photos from the 16th photo onwards. The fabric is stretchy. It fit snugly on me, and I am 162cm tall with a standard build. Photos 14 and 15: There are a few scratches and some pilling. Overall, it's in good condition and not very noticeable. I will ship it as compactly as possible.
