Thank you for viewing. The size is 80cm. I didn't see any noticeable stains. I wore it 2-3 times. Since this is a used item worn by a child, there may be some overlooked stains. Please purchase if you understand. We may not be able to offer a discount as this item requires shipping costs. We apologize for that (;o;) It will be shipped compressed. Wrinkles may occur due to folding. [Discount] I am also selling many other children's items. We will offer a discount for combined purchases, so please comment if you are interested ^_^
