Elton John hosts an annual post-Oscars party, which supports the singer's AIDS Foundation. His star-studded event last night (March 2) featured the likes of Kim Kardashian in a cherry red gown which showed off her bazooms and Vanessa Hudgens in a metallic, fishtail gown, among others.

The Sisters Kardashian each represented her unique style. While Kim wore crimson, Khloe went with a maroon velvet body con gown that clung to each curve, while Kourtney rocked the menswear trend.

Doe-eyed beauty Sarah Hyland was adorbs in her strapless black and white dress, which got a pop of color from her ruby slippers. This frock looks like something Ariana Grande would wear, does't it?
