Sexiest Dress for Your Shape

Before
Who: Kasia Pilewicz
Her dress issue: "A lot of dresses are tight on my hips," says Pilewicz. "But ones that are boxier, like this one, make me look big all around."

If you're curvy
Opt for a V-neck. Fashion truth: V's help elongate your body.

Make sure your dress goes in at your waist-it's the smallest part of your body. Not working? Add a belt!

Showing off the curve of your legs is always hot.

Before
Who: Caitlin Fairchild
Her dress issue: "I thought that the blousiness of this style would camouflage my hips, but instead it accentuated them," says Fairchild.

If you're bigger on bottom
Bare your shoulders. It gives the illusion of width on top to balance your lower half.

Cinch your waist. Tent or drop-waist styles actually make you look bigger all over.

Choose a flowy skirt. It'll conceal your lower half-without clinging.
