we're Obsessed!

There are your basic, totally serviceable, one-piece bathing suits. And then there’s...this one, a less-obvious choice, perhaps, for pool day with the kiddies (unless your swimming spot is in Vegas). But bear in mind: The built-in boning and adjustable corset-tie front (don’t worry—it zips up the back, so you can get in and out easily) will have you looking like one hot mamma.

$790; call 212-965-0229.
