I've only worn this once, so there are no noticeable stains, but please understand that this is a used item before purchasing♡ Size: M! The design is very cute♡ The waist is elastic, so it's loose and comfortable to wear, and I recommend it☺︎ For those who like AG by aquagirl, it's first come, first served! I'm selling a lot of summer clothes, so please take a look☺︎ I'll offer a discount for multiple purchases!
