PS: Do you have your own perfume-wearing or spritzing technique?
KS: I like two shots right here [points to both sides of her neck] after I take a shower. I like to do one over my clothes, too — it stays on longer.
PS: What does the Balenciaga Rosabotanica fragrance ($52) smell like to you?
KS: Everyone has a slightly different impression of it, but my take on it is that it's a little muskier than Florabotanica ($50), but it feels related. It's a little warmer. You can really pick up the rose. I don't wear much fragrance. I don't have a collection of perfumes, so I am glad to have both of them, because they are really very different. This one feels more night, and the other one definitely feels more day.
PS: Every girl is jealous of your naturally beachy hair texture. Describe your hair routine.
KS: I like surf spray. I don't do much. I'm lucky; I don't have to mess around with blow dryers and stuff. I use dry shampoo and surf spray and mess it up as much as I can. To get texture, I basically crunch it up — it's not too difficult to achieve. [Laughs] My hairstyle is sort of messy.
PS: You seem to be drawn to more dramatic eye makeup on the red carpet. Why do you like to play up your eyes?
KS: Typically, I am pretty plain and not too concerned with makeup and stuff. I dress really practically, so when I do red carpet things, I like to go extreme on the other side of it. I really like working with people who love what they do and are a bit more bold. If you're going to do that job, it's always more interesting to find artists and not people who just want to get it done. It can be fun to find different aspects of myself, since it's not usually what I do.
