While the leading ladies have become a hit for their retro styling on-set, sultry redhead Christina Hendricks and the petite Elizabeth Moss proved they're just as hot in 2010's latest looks at the premiere party.
Christina - aka Joan Holloway - stunned in a high-neck lace D&G mini, while Elizabeth (Peggy) sported a one-shoulder figure-hugging emerald-green cocktail dress. Both ladies opted for a barely-there make-up look and looked glowing as they posed on the red carpet with a dapper looking John Hamm.
The last series ended on a serious cliff-hanger and the as the latest installment begins a year on in 1964, it's all change for Betty Draper and a wardrobe overhaul for the whole cast, as mod fashion sweeps the set.
We can't wait for the ladies, and the men in their sharp suit too, of course, to saunter back onto our screens here in the UK.
