I'm selling this item because it didn't suit me after I tried it on after washing it a few years after I bought it. There's no tag, but I believe it's 100% cotton. I remember the purchase price was around 17,000 yen. I'm offering it at a lower price, so I appreciate your understanding. It's see-through when worn alone, so please be careful. It looks lovely worn as a dress, but I think it would also be stylish with jeans or wide pants.
