This was in a box of swimming items we bought at auction. It's size 12 and is brand new with label attached but there's a stain on the backside area (see photo)! It looks like ink, it might wash out but I've not tried. It would be OK if you're always going to wear shorts over it, or could make a bikini top from it. Or if you're not bothered that it looks like you've had a little accident!
Also a grey speedo swimming hat.
