What are you wearing?

A navy blue, strapless Armani dress, silver Jimmy Choo sandals and my own jewelry, which isn’t designer—it was a gift.

How would you best describe your style?

I would say my style is colorful. I like figure-hugging clothes, and I try to be stylish while still remaining classic. I also like to be as different as possible while still flattering my figure.

What’s your favorite go-to outfit?

I have a black wraparound dress that I got at Whistles, a boutique in London, that I love. It’s saved me in a lot of situations.

Any favorite beauty products?

I’m a Dior fan, and I love Esba moisturizer. I also love Kitten [shimmering powder] by Benefit and Stila lip gloss.

Who are your favorite designers?

I love Armani, and I like Alice Temperley and Valentino—he makes beautiful clothes.

Where do you like to shop?

I live in London, so my favorite shops there are Whistles, Zara and Top Shop—they’re all great fun.

What are you looking forward to wearing this summer?

I’m really looking forward to trying a short jumpsuit—I think it’s classy but comfortable. And I love anything green.

What’s the best outfit you’ve ever worn for a role?

Once, while I was playing a character in an English drama, I got to wear a 1920s red dress with gold shoes and a black wig—very dramatic and vintage. And when I was playing Fiona Hicks in The Deal I got to wear lots of amazing, feminine-feeling period costumes as well. Costumes really change the way you behave, right down to walking and sitting.
