If it's not fun, I'm not going to do it.

Only hire people you want to have dinner with.

But as an adult working in the fashion industry, I struggle with materialism. And I'm one of the least materialistic people that exist, because material possessions don't mean much to me. They're beautiful, I enjoy them, they can enhance your life to a certain degree, but they're ultimately not important.

I am a spiritual person in an eastern religion kind of way. I learned that happiness for all of us is a switch that you flick in your brain. It doesn't have anything to do with getting a new house, a new car, a new girlfriend, or a new pair of shoes. Our culture is very much about that; we are never happy with what we have today.

One of the most important things is to figure out what your look is — I don't wear this black suit-white shirt combination all the time to try and be iconic — but because I'm most comfortable in this. Cary Grant never turned up in a pink jacket and hot pants and I don't feel the need to experiment when I know I like dressing this way.

My grandmother was probably the first person who I thought was beautiful. She was incredibly stylish, she had big hair, big cars. I was probably 3 years old, but she was like a cartoon character. She'd swoop into our lives with presents and boxes, and she always smelled great and looked great.
