Eva Mendes. She would be (as Jada Pinkett-Smith put it in 'The Women') fiiiiiiiiine in this dress.
Either Kate Hudson or Camille Belle I can't decide.
Marcia Cross/Nicole Kidman (they're basically the same person really)
Carey Mulligan (NORRRRRRR)
Angelina Jolie (hate her - love the dress)
Michelle Obama - I swear this dress was designed for her.
Tina Fey (or me, 'cause I'm planning on becoming Tina Fey).
I can see Kim Kardashian in this - even though I'm still not entirely sure how she's famous.
Anne Hathaway would look stunning in this dress
Someone striking enough to jazz it up a bit - maybe Zoe Saldana, but with a red or green sash not black.
Christina Hendricks (they'd have to let out the bust a bit...)
Anna Kendrick (she's so cyooooooooot)
