Rachel McAdams in Naeem Khan at Vanity Fair Party 2016

The fashion buzzword for Rachel McAdams at Sunday evening's Oscars in Los Angeles was elegance. After stunning at the show in a forest-green August Getty Atelier gown, Rachel changed into her second gorgeous look of the night to attend Vanity Fair's afterparty at the Wallis Annenberg Centre For the Performing Arts.

Working with stylists Mariel Haenn and Rob Zangardi, Rachel selected a beautiful, sequinned gown from New York designer Naeem Khan for the bash. She finished her outfit with NIWAKA Fine Jewellery and a pair of sky-high silver stilettos.

Perhaps the best part of Rachel's Academy Awards look was the fact that her beauty look was done by none other than her sister, makeup artist Kayleen McAdams. Kayleen walked us through Rachel's Oscars makeup, detailing how the two created a "sexy" and "sultry" effect.
