I have long loved vintage bathing suits. I have picked up deadstock one pieces from thrift stores and etsy that I have almost worn out. They have the best prints and cuts. I have two saved that I want to have reproduced because they are so flattering.
I also enjoy sporting a rash guard. I learned this trick long ago as a way not to have to slather on a ton of sunscreen. Plus I think they are cute in a Bond girl sort of way. I would be over the moon to find a Pret-à-Surf zip front on sale. I just bought a couple of styles from J.Crew on clearance. Under $30 bucks a piece. I think I might even run in them.
