Overall I was a little disappointed with the gowns this year, there was no-one that really stood out & that looked out of this world amazing to me...However these are my Best and Worst picks from the 2010 Oscars (including after parties)
Best
Rachel McAdams in Elie Saab Haute Couture So different and love how she kept everything else fairly simple. Very elegant!

Kate Bosworth in Valentino at the Vanity Fair after party.
Victoria Beckham at the 2010 Elton John AIDS Foundation's Oscar Viewing Party wearing a nude gown from her own 2010 fall collection. Really like this dress, it looks classic and flawless on her.
Jake Gyllenhaal in Burberry (HOT - need I say anymore)?!
I actually also really liked Maggie Gyllenhaal's dress. The blue just made her look very vibrant.

Miley Cyrus in champagne coloured Jenny Packham dress
Am normally not much of a Miley fan but think this dress is stunning and love her makeup & hair combination.
A little special mention, just because I think he's so hot! Ryan Reynolds in Tom Ford ♥ Sigh...Scarlet is one lucky girl!!!
Worst
Jennifer Lopez in Giorgio Armani Prive.
Don't like the fabric and it's just plain unflattering in some angles, sorry J-Lo!
Mariah Carry in Valentino.
Too much leg for the Oscars and just "no"
Charlize Theron in Dior Couture
I usually love her style! The dress fits wonderfully on her amazing body but I just don't really like the rose details on her chest. Plus don't like the red lipstick with this outfit...
Cameron Diaz in Oscar de la Renta
I think the dress is gorgeous but the hair and makeup is too much for me with this super sparkly dress. The dress paired with a simple loose updo & gold smokey eyes with soft lips and I would have loved it.
These were MY picks and therefore completely my opinion so feel free to disagree :) Who's look did you love or hate?
