All you need is love — love and theme parties, apparently. Real Housewives of Beverly Hills ladies past and present got together this weekend, looking très chic as they intended a party inspired by Moulin Rouge.

Camille Grammer took her costume very seriously and was happy to show it off on social media.

Kyle Richards loved her get-up so much, she wants to wear it every day (Lisa Vanderpump couldn’t agree more).

Lisa Rinna rocked a sexy corset, top hat, and some seriously smoldering side-eye.

Speaking of flawless fashion, there's still time for you to vote for your favorites in this year's Real Housewives Awards. Vote for Rookie of the Year below, and tune in to Watch What Happens Live on Monday, September 14 at 11/10c to find out who will take home the awards!
