Hot pink is definitely Kristen Bell's color. The Forgetting Sarah Marshall star's high-waisted miniskirt balances out her loose fitting champagne blouse perfectly.

When don't the JoBros look on-point? Kevin chose a classic dark jacket and unbuttoned shirt. Nick deviates from the conventional with his white suit and purple V-neck (complete with pocket square). And Joe gives an old-fashioned look a new twist by ditching the jacket, opting for short sleeves and wearing blinding white tennis shoes.

Leighton Meester and Ed Westwick look like they just rolled out of bed, no? Meester looks a bit more put together with her emerald-green dress, but the scarf and pit-stained shirt on Westwick are fashion don'ts.

Rainn Wilson can get away with a lot on the red carpet, including an untucked button-down beneath a blazer. The shades and sneakers, by far, make the outfit.

Sophia Bush looks gorgeous in this purple, floral empire dress. The strapless neckline and high slit make it only that much sexier.

Summer Glau has the same length problem as Hayden Panettiere. Perhaps she should have went with a different neckline to cover up those tan lines as well.

This white, strapless, tea-length dress probably isn’t the best choice for Kim Kardashian. Her look is very dark and exotic, but coupling that with the white dress and bright-red lipstick makes her look a vampire.
