Cute casual blouse. There are marks on this blouse on the waist, I only wore it once and washed it so I don't know if they came from wear? They're not noticeable when you're tucking it into a skirt or pants, or if you wear it under a JSK. I didn't try to clean them locally, so i don't know if it can be cleaned.
The material is chiffon I think, the tag says M but it fits a 100 bust. Last seller said it could go up to 110 bust but I don't recommend it. Overall it's very cute, light and could work for more sweet coords and more otome ones.

rest of the measurements from the seller I bought it from:

waist: max 90 cm
length: 63 cm
short sleeves: about 24 cm in length
sleeves circumference: max 32 cm
again, bust around 100 cm.
