I haven't worn it much, so it doesn't seem to have any noticeable stains, but there is some wear and tear. The waist is elastic. Width: Approximately 41cm Length: Approximately 73cm Please note that these measurements are approximate, as they are taken by hand. I would appreciate it if you could understand that this item has been stored at home. There are no smokers in my family. I don't have any pets either. I will use recycled packaging materials. It has frills, so it covers your arms a little! I think it would be cute as loungewear too ♡
