Your character, Joan Holloway, has such a distinctive look, with her hourglass figure and glamorous makeup. How does your real style compare?
I've started to wear more form-fitting dresses to show off my waist. And everyone thinks Joan wears red lipstick on every episode, but she's usually wearing coral. I love ruby lips in real life.
Is your taste retro, then, like Joan's?
I'm more girlie than Joan. Her character's very coiffed and put together, so the producers wanted to have her hair up. It takes about an hour-and-a-half for hair and makeup because her updo is like a sculpture. I'll usually bring a book or my knitting — I made my husband a steel-gray fisherman's sweater for a wedding gift. Once in a while, Joan gets to wear her hair down, but I feel like it's wrong; it's not her. When I'm not working, I love crazy rock-and-roll curls.
So without the bouffant, do people still stop you on the street?
At the beginning, I hardly ever got recognized because I looked so different than I do on the show. Now just the red hair is a signal. But if I wear a hat, people don't notice me as much.
You're actually a natural blonde — and have been dyeing your hair crimson since age 10. Is it a lot of upkeep?
The ultimate daily digest for women of power, purpose, and style.
We color my hair every other episode to make sure it maintains the same brightness. I use a lot of Redken Color Extend conditioner. It's like sunblock for hair!
You've been showing more skin on-screen. How do you prepare?
If my legs are showing, the makeup artist adds a tiny amount of foundation to body lotion and rubs it in. Now if I have an event to go to, I'll buy CoverGirl foundation and mix it in with my lotion.
How do you maintain your figure?
My new obsession is Häagen-Dazs Low-Fat Frozen Yogurt in Dulce de Leche. It's a revelation. I can't believe it's low-fat. It doesn't make any sense, it's so good.
Any other beauty essentials?
I love perfume. I have 10 L'Artisan Parfumeur scents. Right now I'm super into the amber, but they also had a mandarin that's absolutely amazing. I bought it when I did the pilot for Mad Men, so every time I spray it on, it reminds me of how excited I was to start the show.
