Steep - $64.99 J Crew (above)

Rash Guards or "rashies" as they call them down under where they originate from,  aren't just for kids. Made originally for surfers to prevent water rash and sun burn, they are now seen on beaches everywhere. Commonly made of spandex and nylon or polyester, they do a great job of protecting you sensitive chest, back and arms from dangerous UV rays. Ladies, they look super cute with a bikini bottom and I think can actually look quite sexy.  They are great to wear when out on the water where they sun's rays can be particularly dangerous. Find the above stripped rash guard here.
