Jennifer Lopez

Ok, so the pic is a little hard to make out, but if you watched American Idol this week, you know exactly why J.Lo makes our list. She paired a super-hot sequined dress with a sweet, half-up hairstyle.

Zoe Saldana

We love this dress's kicky, ruffled hem—and Zoe looks ultra-pretty with her hair up, highlighting her swan-like neck.

Emma Roberts

Jean jackets are back in a big way—this washed-out version looks great with black cigarette pants and nude pumps.

Camilla Belle

From her eyeshadow, to the sexed-up t-shirt dress, to the great clutch, Camilla is a silver belle—and the pockets are pretty amazing.

Jennifer Hudson

We're crazy over stripes right now, and this mini-dress is one of the best incarnations we've seen. Not to mention that Jennifer Hudson's bod looks bangin'.

Megan Fox

Sure, we all know Megan Fox is foxy, but she looked especially glam in this neon number—and what you may not be able to see is that the dress has a racy keyhole from the neckline to the waist.
