Vintage swim trunks or beach shorts for boys or unisex

Vintage swim trunks or beach shorts for boys These shorts are in like new condition and are so well made! They are nice and durable material and have built-in mesh lining and a little button pocket in back on the right. They are super retro! My best guess is that they are from the 1960's. They look like deadstock but no tags. 77% Cotton 23% Polyester Made in Korea Red/blue Size 10 Pls see my other listings as I have these shorts in other colours and sizes.
