Christina Hendricks at the ‘Mad Men’ Gala Event in Paris

An old fashioned style rule states: when you reveal one attribute, balance it by covering up another. So when one of’s Most Desirable Women of 2010 Christina Hendricks covers it up at The AMC Mad Men Gala Event at Hotel Royal Monceau Raffle on Feb. 8, we wondered… what was she wearing the night before?!

Hendricks and hubby, Geoffrey Arend, were spotted the day before shopping at Soleil Suare Lingerie, which gives indication that whatever it was – it was spicy! So spicy that she wore a high necked, bright blue dress departing from her more revealing wardrobe choices the following day at the Gala, which honored Mad Men creator, Matthew Weiner.

Known for wearing high slits and low cuts to accentuate her God given curves, as seen at the 2011 SAG Awards last weekend, Hendricks admitted to NY Magazine last year that it hurt her feelings at first.

“Anytime someone talks about your figure constantly, you get nervous, you get really self-conscious,” she said. “I was working my butt off on the show, and then all anyone was talking about was my body.”
