Purchased for around 10,000 yen and stored at home after a few uses. It's black and made of thin fabric, but it's not see-through. There's a chiffon ribbon around the collar, and you can adjust it freely by tightening it or loosely tying it to show off your décolletage. It's a size M, but it has a relaxed fit. The frills on the sleeves are a layered design of lace and chiffon, with multiple tiers. I believe there are no stains. Thank you for your understanding, as this is a used item.
