Disliked:

Sandra Bullock - blah
Mariah Carey - awful
Miley Cyrus - bad, too much like lingerie, too adult/sexy in a bad way
Zoe Saldana - mess, hated it
Jennifer Lopez - too bootilicious for me, like a bad wedding dress
Penelope Cruz - misshapen and unsymmetrical neckline
Maggie Gyllenhaal - hippie, like a beach coverup
Gabourey Sidibe - don't like the asymetry in the neckline
Charlize Theron - roses on breasts? a bit obvious. Also, the bottom of the dress is wrinkled
Tina Fey - don't like the asymetry in the neckline
Rachel McAdams - sits too low on the breasts, looks like it will slip off at anytime, combined with the thin material
Molly Ringwald - the purple one-shoulder. Kinda hated it.

Undecided:

Queen Latifah - eh, the fit is good (she looks great), but I'm not a fan of satin, and it looks wrinked.
Kate Winslet - I generally like the gray/steely color, but it's too plain and too much Joan of Arc
Mo'Nique - I don't know. The fit is too tight, and I don't think I like the fabric.
Sarah Jessica Parker - another satin that looks too flimsy/nightgown-ish, although the embellishment at the neck is pretty and the shape is nice, and the material smooth.
Sigourney Weaver - boring


Liked:

Vera Farmiga - really really liked the big ruffles, dramatic and awesome
Kristin Stewart - loved. It's black but shiny and wonderful with texture and shape. Very sexy.
Meryl Streep - elegant quiet, age-appropriate
Anna Kendrick - beautiful pale pink, romantic and dreamlike
Hellen Mirren - flawless, gorgeous
Demi Moore - not bad. If only the orange color of the dress didn't match her skin color.
Cameron Diaz - the overall look (hair, makeup) is fantastic, very beautiful/glamorous.
