Luckily I don't have to buy shoes anymore, because I design them! I'm off tour, so I can dive in and create the shoes that I want for my line. But okay, I did buy a pair of vintage combat boots because they were so beaten up - I had to have them.

When we were in the design studio I always was pretending like I was in a closet asking my friend before I step out into the world what do I look like? And everybody wants that honest friend before they go and go to dinner or go to an event.

I am extremely involved in the design process of both my brands, Winter Kate and House of Harlow 1960.

What I've learned from different designers is that it's key to be true to who you are and your vision. That's always been my line of thinking. Working through the whole design process, I don't want to create something I wouldn't be proud to wear.

I learn my lines while on the golf course. I try to do two or three things at once. I have ideas for books all the time, I have ideas for paintings all the time, and I write them all down. I take my sketchpad and my iPad, which I design on, and I do sit down and do specific tasks at specific times.
