I don't work with Sia every day; it depends what we do, whether we do performances or music videos, so the schedule is weird, but when we're off, we always try to see each other in between. We just hang out; we went to brunch one time, but for the most part I go to her house, and we eat and watch TV.

I don't think fashion has to change every five minutes. I'd like these to be clothes you can wear for a long time - ten, 20 years; pass on to your daughter. Why buy vintage when you can open your own closet!

When you're competing, you have to wear a sleeve that goes all the way down to your wrist. When you're training, you usually don't wear long-sleeved leotards, so there's a difference between training and competing.
