The easiest way to balance a bottom-heavy figure is to choose a little black dress that skims over the lower half of the body. Fuller skirts, like this Monique Lhuilllier dress, disguise heavy hips, while showing off the waist. A fitted halter or strapless silhouette -- which accents a trim upper body -- is very flattering for bottom-heavy figures.

Don't worry: you don't have to look matronly to cover up flabby arms. The trick is to keep the sexy element with embellishment or peekaboo cutouts on the little black dress. This sheer-sleeve dress is another great way to get some sex appeal and still conceal arms.

The perfect little black dress for a smaller frame elongates and flatters like this fringed Donna Morgan jersey shift. More flattery: look for a dress shape -- like horizontal seaming -- and is scaled just right for your figure. Avoid too-cutesy looks (like puffed sleeves or giant bows) so you won't look little girlish.
