This is a WILLFULLY roll-up sleeve long JK (jacket-like) OP (one-piece). I purchased it as a used item on ZOZOUSED. I've only worn it 2-3 times, and there are no noticeable scratches or stains. It's very cute, but I (height 155cm, and I rarely wear heels these days, and I squat down a lot) can't quite pull it off, so I'm hesitant to sell it. I might withdraw the listing because I'm still unsure, but if someone likes it and wants it, I'll consider it fate! It's made of polyester material, so it's smooth and easy to wear.
