There are no stains, but there is some fraying like in the third photo. Please be aware of the pilling and signs of use. It's not noticeable at a glance. Please take a good look at the photos. The elastic isn't stretched out, and they can still be worn, so please use them for playing outside. They fit like a size 75-80. Thank you. They're not thin and flimsy; they're a moderate thickness.
