Olivia Wilde was my Best Dressed of all those who attended the Oscar after parties.

The stunning actress wore a buttery yellow RM by Roland Mouret “Hydra” gown.

The organza ruffle front gown was a beautiful colour on her, which she paired with a maroon clutch and matching Ferragamo satin heels.

Bold red lips and loose waves completed the look.

Roland Mouret also dressed Anna Paquin for the 2010 Vanity Fair Party.

Anna has been taking a lot of risks lately wearing Viktor & Rolf, Alexander McQueen and Marios Schwab, so her black RM by Roland Mouret “Latona” dress feels a bit tame in comparison to her riskier ensembles.

She would’ve totally rocked the orange version and I’m really surprised that on her current form she didn’t go for it.

The actress paired her dress with a Maia N python box clutch and a House of Lavande vintage seven strand gold ball necklace.
