PS: Are there any '90s trends you would rock now?
KU: I have a pair of Birkenstocks. . . . I don't know if I'll wear them. I'm warming up to the idea [laughs].
PS: Switching gears a bit, what about the best piece of fashion advice you've ever gotten? Anything that's stuck with you?
KU: My mom always told me that it's all about confidence; it's not about what you're actually wearing. Anytime you walk into a room, just smile, and nobody will even look at what you're wearing.
