The size is marked as M, so I have listed it as size 80. This is a set of 2 suspender leggings. The black leggings have some loose threads on the tag, so I have marked them as "slightly scratched or dirty," but there are not many pills or signs of wear, and I think they are in relatively good condition! Purchased online. I want many people to see this, so I am borrowing the Birthday tag, but these are not Birthday brand clothes. Please refrain from purchasing if you are sensitive.
