January Jones may have missed the Los Angeles Premiere of Mad Men Season 4, but she definitely made up for it in NYC over the weekend. Joined by her gorgeous costar, Elisabeth Moss, the blond beauty walked the red carpet in absolutely awesome style and Breaking Celebrity News has all the details of her A-list look!

January opted for a white hot halter dress from the Versace Resort 2011 collection, which hugged her slender figure in all the right places. The lightly embellished mini was impeccably draped, exposing her sexy back in a criss cross of fringe. Finishing the look off with Brian Atwood square-toed, nude patent heels, the flawlessly-faced star couldn’t have looked any better!
