I bought this a few years ago and have worn it occasionally. The size is 38 (M), but the waist has elastic in the back and is roomy, so I've listed it as a size L. The length is about 102cm, and I think it will be a length that covers the knees. The skirt part is flared, and you can wear it cutely by marking the waist with a belt♡ There are no noticeable scratches or stains, but please understand that this is a used item before purchasing. Please be sure to check the notes in my profile.
