If You're Athletic...

Sue Molnar, 46, a Spinning instructor, works out six days a week to maintain her lean, toned figure. "It took until my 40s to love my teenage physique," she says. "But with a small bust and hips, I'm always looking for styles that add femininity." The vertical axis of this color-blocked tankini (Pret-A-Surf, top, $160; balances Molnar's shoulders; the solid bottom ($140) breaks up her long torso.
