Boys Swimsuit set of 4!! Size 18 - 24 month!! And my son even wore into 3T. 2 suits are bottom shorts style with short sleeve rash guard tops with one being a long sleeve rash guard with shorts. One is a one piece zip up style suit. 2 are from old navy, Nemo one is from Disney and one is Cat and Jack. Great for vacation to have a few suits so your little one doesn't need to put a wet suit back on after nap time!!
