PS: How has your beauty look changed over time, especially since you came into the spotlight?
KS: I've always — with everything — gone with my instincts about things. I can put more stock in my instincts now, because I know myself a little bit better. I typically have an easier time finding exactly what I like and what I'm comfortable in. You do it for a couple of years, and you know what you gravitate toward.
PS: Do you feel like you have more of a say now?
KS: No . . . I don't know if people have this idea that you're told to do things and wear things — and maybe some people are. I've been lucky and always worked with really good people. I can definitely take credit for all of the good and the bad (laughs). I have definitely had to wear a lot of dresses.
PS: What goes into your skin care routine?
KS: I actually use Proactiv. I've used it forever. When I was a teenager and had skin problems, it was awesome, and I feel like I am addicted to it now. I feel like if I stop, I will get skin problems again. You see all of these commercials and stuff, and I am definitely an honorary spokesperson. I think it's awesome, and I talk about it a lot.
PS: Which of your past characters aligns most with your own beauty look?
KS: It was fun to play Joan Jett [in The Runaways]. She is a huge style icon — for me, personally, and just in general. That was so specific. But it was fun to step into her shoes because she is so extreme. The most "me" was probably — oh, man — that's the thing, I am really simple. I loved doing On the Road. That's a period piece, and I don't specifically identify with the clothes I was wearing. It was more the style in which we wore them, the mood of it. I like thing being a little worn-in. They're all really comfortable in what they're wearing, and they're not really thinking about it, but they love it. That's usually what I go for.
