Jennifer Lopez is looking gorgeous as always in this gown, but the sequins and sheer cut meet at an awkward point, shortening J.Lo's iconically sexy frame.

The Les Mis star was the picture of understated elegance in a navy Zac Posen trumpet gown and a long pendant necklace by Lorraine Schwartz.

This dress is fun with its futuristic design, but the stark white, neon piping, mesh panels, and thigh-high slit make the dress too busy.

Kerry was pretty in pink in a bedazzled strapless Miu Miu number. Bonus points for the matching clutch and shoes.

If that skirt were black, we might not be as bothered by the thigh-high front.

The actress looks beautiful but we would prefer this gown in a different metallic.

The Mad Men actress looked pretty—and age appropriate—in a sweet floral tea-length frock from Delpozo.

We would have enjoyed this look if it had an entirely different neckline and sleeves.

Lucy Liu needs very little to compliment her stunning looks—this printed fabric seemed like too much.
