Low Tee makes men's bathing suits from vintage t-shirts (props for recycling). The suits are fully lined in Lycra, and have elastic around the legs and waist, which also has a drawstring. Because the suits are made from vintage t-shirts they are all one-of-a-kind (which we also like). And if you ask nicely you could probably send in one of your own shirts to be converted into a suit. Suits are well-priced at $45 and available online.
Thanks, Rob.
