Rita Ora dared to bare nearly all in a see-through dress at the Vanity Fair Oscars after-party. The singer's tattoos could be seen through the sheer black mesh gown and she appeared not to be wearing any underwear.
Not to be outdone, Russian model Irina Shayk also wore a daring black mesh outfit that left little to the imagination.
At the other end of the scale, Australian singer/songwriter Sia covered up, obscuring her face with a platinum blonde wig. At least we think it was her.

The Vanity Fair party is one of Hollywood's most glamorous events, attended by Oscar winners, nominees and film royalty.
Fashionistas will no doubt be poring over the outfits worn by the celebrities in an effort to identify trends.
