Oscar wardrobe changes -- What stars like Amy Adams and Heidi Klum were wearing on the red carpet, on stage, and for the parties

Amy Adams
On the carpet: Proenza Schouler’s emerald silk twill
On the stage: L’Wren Scott’s black wool crepe to perform ”Happy Working Song”
Winner: When you’re singing your heart out to invisible rats and cockroaches, there’s a decent chance we won’t be eyeballing your dress. That arrivals garb, on the other hand, got our attention. Green!

Penélope Cruz
On the carpet: Navy blue Chanel Haute Couture
For the parties: Black single-shouldered Versace
Winner: Jeez. Rock and a hard place, Penélope! While the Karl Lagerfeld-designed organza number appears to be trying to escape from itself (and the actress used up her feather credits last year), her Jane of the Morbid Jungle look ain’t much better. Draw!

Markéta Irglové
On the stage: J. Mendel’s blue silk mousseline to perform ”Falling Slowly”
For everything else: Also J. Mendel, also silk mousseline, this one in black
Winner: There’s nothing flattering about that first unsupported bodice, so thank heavens for the black gown, an elegant, unpretentious choice. You’re a long way from the streets of Dublin, dear. Kudos!

Heidi Klum
On the carpet: Haute Couture by John Galliano
For the parties: Roberto Cavalli
Winner With its high collar and epic skirt, the Galliano ensured there wasn’t a soul who didn’t see Klum make an entrance. But that mini is fierce (to borrow a phrase). What makes us think this vote might split down gender lines? Rawr!
