New PJs/Swimsuit??

•Ok so I couldn't tell if these are PJs or swimsuit because of the mess lining underwear but either way these things ROCK!! •Also the tag says XL...no way these are XL please reference back to pics for measurements I listed them as a small only because my son is 17 and wears a small these fit perfect. Only way these could maybe be a XL is if maybe it's like a YXL?? •Everything is cross-posted NEW NO TAGS A11
