There are 2 fixes on this item. One near crotch and one near the leg. One button is different from the other ones, and this is sheer. This seems like loungewear or pajamas. It seems like the 60s or 70s. This seems like an adult XS? Please check the measurements. I did not find any stains, but some stains and a vintage scent might appear depending on how long this has been sitting. Pit to pit is 17 inches, waist across is around 18 inches, inseam is 18 inches, shoulder to crotch is around 26 inches. Thanks! e
