Cotton overalls with adjustable straps. They are an off-white, cream color. I purchased them at the Gotemba Outlet about 3 years ago and have worn them less than 5 times. They have been stored in my closet at home since then. There may be some signs of wear, such as pilling, but I don't see any noticeable stains. There may be oversights, so please understand that these are items stored at home by a private individual and are used before purchasing.
