Do blonds really have more fun? According to Elisabeth Moss, they do in the wardrobe department! We caught up with the star at the Alice + Olivia presentation at New York Fashion Week to get the details on her platinum pixie. “I had the same brunette color for two projects in a row, and I wanted to do something really different,” she told us. “What’s great about being blond is that you can wear any color—even darker colors. Blond hair is almost like an accessory in itself!” Between her edgy new color and Mad Men‘s 17 impressive Emmy nominations, we had to ask about the special ensemble she’ll wear to the Emmys in celebration. “I don’t have an Emmy dress color yet, but it’s opened up options,” Moss said. “It could be anything! Whereas, when you’re a brunette, you need a little bit more color.” We can’t wait to see what she picks!

And Elisabeth isn’t the only star who has drastically changed her hair this year! See more celebrity hair makeovers below!

In a dramatic departure from her retro coiff on Mad Men, Elisabeth Moss surprised us when she stepped out with a platinum pixie last week. We caught up with Tommy Buckett and Caroline Buckler of the Marie Robinson Salon, who worked together to give Peggy Olsen a brand new ‘do. Both stylists decided to go with an edgy style that really pushed the envelope since Moss wanted to go shorter. “I tweaked the color a bit to go with this cut,” Buckler said. “Elisabeth’s skin tone is perfect for this shade, which makes her eyes really pop.” Thinking of making the cut like Moss? Keep your hair texture in mind before heading to the salon. “This style works for girls with straight to wavy hair,” Buckett said. “The soft, flat bang gives it a modern look.” We agree!

Now this is what we call a blond ambition! Elisabeth Moss (in Dolce & Gabbana) unveiled a new platinum blond pixie at last night’s New York City premiere of For a Good Time, Call. The look is a dramatic change from the retro Mad Men coiffs she sports as Peggy Olsen, and is such a major change, it reminds us of Miley Cyrus and Ashlee Simpson‘s edgy cuts. But this isn’t her first time as a blond! The star, who is a natural brunette, added sunny highlights to her chin-skimming bob last year. Do you like how her new haircut? Tell us in the comments!

What can you expect to see on the red carpet at Sunday’s Golden Globes? “Lots of color,” says Estee Stanley, stylist to Lea Michele (shown right), Jessica Biel and Elisabeth Moss. “It’s the most fun any girl who loves clothes will ever have.” InStyle‘s Fashion Director Hal Rubenstein agrees. “This is going to be a big color season,” he said. He predicts Best Actress nominee Anne Hathaway (shown left) will go for something bright and bold. “Anne loves dramatic fashion,” he said. “She’s not afraid of wearing a big dress, big gown, lots of sparkle, intense color. I think for the Globes what we’re going to see on her is something big and shiny.” Watch Rubenstein’s Award Season Preview video for more predictions after the jump. More
