I've only worn this once, so there are no noticeable stains, but please understand that this is a used item before purchasing. The color is a bit brighter than it appears in the photos! Please refrain from purchasing if the color is different from what you expected. Size: M! It's sheer, so I recommend wearing an inner layer. The floral pattern is eye-catching and very cute! I'm selling a lot of summer clothes, so please take a look! I'll offer a discount for multiple purchases!
