It's Friday, yay.

And while I mostly wore casual summer staples like white jeans and little dresses to work this week, the stars had a whole different "work" wardrobe going.

I guess when you're walking a red carpet, you just may want to step it up a little, right?

Here are five of the best:

MARION COTILLARD: Love, love, love this! She looks like a swan and I mean that as a compliment! (No Bjork swan dress here!) Her porcelain neck and arms look long and elegant in this yummy Dior frock. The detailing on this cream silk organza, embroidered dress is exquisite paired with her delicate features. She keeps things from getting too sweet though by adding a little edge with spiky, tough Louboutin heels.

ANNE HATHAWAY: This Prabul Gurung is absolutely stunning. It's very much a Grecian goddess kinda gown and it makes the "Dark Knight Rises" star look super tall and statuesque. I like the peplum and the detailing on the deep plunge, it's a gorgeous gown.

HEIDI KLUM: Sleek in black Francesco Scognamiglio. This woman is a freak of nature -- she rarely, if ever, looks bad! I love her sexy, tousled hair, which perfectly complements the dress, which shows a little leg and a little of the chest area without revealing too much of either. The "Project Runway" star continually makes it work!

LEA MICHELE: Sassy! The "Glee" star's ensemble is age appropriate and event appropriate -- just the thing to rev up all the fans at Comic-Con! This Stella & Jamie ensemble is flirty and fun and the tweed shorts show off Lea's very tan legs. The red shoes give a nice pop of color.

KATE MIDDLETON: Best color of the week! Love her bright, blue Stella McCartney dress. It's not her best look ever, but the dress is flattering on her figure and she adds some sparkle with a $78,000 Cartier necklace from her personal collection.
