This is a knit dress from GU. It's a size M, and the length is just above the ankles on someone who is 160cm tall. It comes with a removable string belt at the waist. (See photo 2) I've worn it twice, but I'm selling it now because it's been stored away since then. There are no noticeable stains or scratches, but please refrain from purchasing if you are sensitive to items stored at home. To reduce shipping costs, I will ship it in a compact state. Thank you for your understanding.
