Anne Hathway looks like she’s having a blast presenting the 2011 Oscars with James Franco tonight.

I would too if I got to play dress up several times in one evening.

The first white look is a Givenchy Fall 2009 Couture gown. The bustier white gown is embroidered with crystals details over the bodice.

For her second look she opted for a masculine look in a role reversal skit with James Franco.

She wore a Lanvin black tuxedo with satin lapels which was paired with matching pants and a Lanvin white tuxedo shirt.

Brian Atwood custom black satin ‘Fiona’ pumps which were covered with Swarovski crystals and a black bow-tie completed her look.

My favourite look is this purple sapphire Giorgio Armani Privé Spring 2011 gown.

The luminescent duchesse satin off-the-shoulder dress with a fitted bodice and a high back slit was paired with stunning silver jewels.

The fourth look was an Oscar de la Renta Fall 2011 one-shoulder silver beaded tassel embroidered gown.

On this occasion she opted for wavy locks.

Which is your favourite look of these 4?
