August is apparently the month for drastic hair changes! The latest celeb to give her skull rug a complete makeover is (former?) Mad Men actress Elisabeth Moss, who followed the lead of Miley Cyrus by going with a really short and really blonde look at the New York City premiere of For A Good Time Call… last night. (Are we seeing the beginning of the end for long, dark hair?!? I blame global warming!)

AMC’s perennial Emmy winning series Mad Men returns for its fifth season with a two-hour premiere on March 25, and on Monday the network released a batch of official cast photos for the upcoming run. Keep reading for the stylized 1960s portraits of the whole Sterling Cooper Draper Pryce gang! (Minus the fiercest and awesomest secretary to ever grace the small screen. R.I.P. Ms. Ida Blankenship.)

Could it be that Elisabeth Moss is relinquishing her role as one-third of the Mad Men Neapolitan hair color trifecta that includes red-headed Christina Hendricks and the very blond January Jones and trading in her brunette mane for lighter locks? Keep reading to see photos of the 28-year-old actress at the 38th International Emmy Awards in New York last night sporting a lighter hair color and wearing a nude-colored gown with some fairly bizarre asymmetrical shoulders.

It must be frustrating having to play third fiddle in the babe orchestra that is the cast of AMC’s Mad Men. When she’s not literally standing in the shadows of Christine Hendrick’s bodacious bod Elisabeth Moss is beside a reincarnated Grace Kelly in the flawless form of January Jones.

But there are some rare occasions in which Elisabeth gets to do an event by herself and when that happens she gets to remind everyone just how hot third fiddle can be! That was exactly what happened at the Cologne Conference in Germany today when little Miss Peggy Olson was the headlining hottie for the Mad Men Season 2 preview party! Check out Elisabreast and her plunging neckline along with Don Draper himself, Jon Hamm!
