Not the fighting-tooth-and-nail-through-the-racks-at-Target-for-your-next-swimsuit type? Prefer to hit the pool with a little more panache? Enter E. Martini. Each spring the SouthPark shop offers figure-flattering suits and leaves the mass-produced stuff to the department stores. With custom tailoring, you can have cups added and cuts made on such lines as Vix, Trina Turk, Carmen Marc Valvo, and Juicy Couture and fashions that span the spectrum — Brazilian, American, and full cut — to create that can’t-live-without suit no one else has.
