It's free size, but I think it's around a size L. The waist is cinched, and it comes with an underslip, so it's not see-through and can be worn in a classic style. You can also wear a cardigan for a clean impression. It's a beautiful item, but it has been stored at home, so please forgive any minor wrinkles. ★ I also handle other clothing items, etc. ↓ #Chloe★Clothing/Bags etc. ↑ Please take a look if you like!
