Want to pick out the women capable of pulling a Baywatch-type rescue? Look for the ones wearing a sporty one-piece suit by TYR or Speedo, says Katrina Ramser-Parrish, a freelance writer who blogs about swimming at Squidkid.org. "I can tell you as a swim instructor with 15-plus years of experience, that style says 'I'm a serious lap swimmer,'" she explains. "Polyester material in the pool lasts long after nylon and spandex suits give out."
Tip: If you're on vacation, treat yourself to a second suit that brings out your poolside persona, and compliments your margarita glass. Try something sporty with a splash of color, for starters.
