I've worn it twice, but I don't see any stains. However, there's a small scratch-like mark in the middle, though it's not very noticeable (see photo 4). Please understand that this is a used item and that I am a private seller, so please consider this when ordering. Size: Free Size Material: 100% Polyester The length is just above the knee on someone who is 157cm tall. It will be folded and sent in a bag.
