This vintage swimsuit was made in the 1950s or 1960s by Ocean Champion. Ocean Champion was one of the first companies to move away from wool and lastex blends, and into modern materials. This box is slightly later than the other pair I’m listing, rephrased to read “The Choice of World Champions” instead of “Chosen by the U.S. Olympic Team”. The pattern and model is the same.
As the box says, the suit is two independent layers, a trunk within a trunk. At this point, the manufacturer Ocean Pool Supply Co., was headquartered in Huntington Station, Long Island, NY.
This vintage swimsuit was made in the 1960s by Campus Sportswear. This was part of the brief resurgence of 1920s men’s styles in the ’60s. This is a late ’20s or early ’30s style, a one piece, with side cutouts. There are belt loops for what would probably be a white web belt. The suit is marked a size 28-30.
These vintage trunks were made in the late 1940s from the new “Day-Glo” fabric, made under patents 2417383 and 2417384. It certainly lives up to the claim of “fluorescent”. They have an elasticized waist (the elastic is still good), a full mesh liner, and a flapped, buttoned coin/key pocket. Postwar California beachwear at its finest. There is some fading, but it blends in somewhat with the shininess and day-glo effect of the fabric. With the waist, I would recommend these for a size 34-36.
These vintage swim trunks were made in the 1930s. They are marked “Guaranteed 100% all wool”. They are belted, with an elasticized belt with zig zag buckle. They have a smell from their old mothproofing, but it seems to have done its job well, I do not see any holes. They are lined in the front.
