I've only worn this once, so there are no noticeable stains, but please understand that this is a used item before purchasing♡ Size: 38! I think it's about a size M☺︎ Measurements are approximate, laid flat, length is about 84cm! The design is very cute♡ It's loose-fitting and I recommend it☺︎ I'm selling a lot of summer clothes, so please take a look☺︎ I'll offer a discount for multiple purchases!
