OOH, LA, LA!
THE A-LIST TURNS OUT TO CELEBRATE FRENCH COUTURIER PAUL POIRET AT THE MET'S COSTUME INSTITUTE GALA
THE MET COSTUME INSTITUTE GALA
Blanchett, the gala's cochair, opted for "an edgy-editorial look, rather than a classic red carpet," says her hairstylist Mark Townsend, pairing her tiered, flapper-style dress with upswept hair.
How did Bullock accessorize her custom-made, hand-painted fuchsia silk chiffon frock? With a platinum-and-diamond Lorraine Schwartz cuff and her husband, Jesse James, and sister Gesine.
After walking the red carpet in this silvery, one-shoulder gown, the Oscar winner hit the stage to perform Dreamgirls
' "And I Am Telling You I'm Not Going," which earned a standing ovation from the crowd.
Calvin Klein Collection
"I really lucked out that it fit," said Tyler, who added vintage Van Cleef & Arpels jewels to complete her look. "This is perfect. I feel like a princess. Unless I spill wine on myself!"
Lopez's silver dress featured a "1930s cowl neck, fully beaded," says Marchesa codesigner Georgina Chapman. "We're stunned every time she wears something of ours. She could wear anything."
Dior by John Galliano
After posing in her fuchsia silk organza dress—topped off with turquoise jewelry from Fred Leighton—Diaz stopped to chat with Gisele Bündchen and Liv Tyler
on her way into the party.

THESE STARS STOOD OUT WITH THEIR GRAPHIC STATEMENTS
Yves Saint Laurent
Wearing an ivory silk gown with black crocodile embroidery, the supermodel—and new face of YSL—walked the red carpet solo, meeting up with boyfriend Tom Brady inside the party.
This vintage frock came from the designer's personal archives. Another personal touch: Olsen's date, shoe designer Christian Louboutin, provided her stiletto heels.
"Mischa and I chose the dress together in Paris," says Valli of the one-of-a-kind, Swarovski rockcrystal-studded confection he created for Barton. "She's very young but very, very stylish."
RISKY RED CARPET MOVES
Simpson "has got a really big personality," says Cavalli, though he admits, "sometimes my things fit her better and sometimes less so."
Vintage Yves Saint Laurent
Dunst (with rocker beau Johnny Borrell) took the gala's early-20th-century Poiret theme seriously in a vintage flapper gown, feathered headband and Fred Leighton jewels.
DRESSING FOR TWO!
Despite walking the red carpet in high heels, Hayek, due this summer, said, "I'm feeling good." Good enough, in fact, to hit the gala's afterparty with fiancé François-Henri Pinault.
Although he altered this gown to fit Watts's growing bump, Posen says the design was always intended "for somebody who's going to be pregnant: It has volume and it's movable."
