I always use a really simple analogy: if you're putting organic food on your table because you care about eating well, shouldn't you be trying to do the same with what you're putting on your body? Our skin is our biggest organ. Everyday you are absorbing things through it. The way that a cream without the right ingredients can affect you, everything you put on your skin matters.

If you feel good about your clothes, you get excited. And I want women to feel good when they're wearing my clothes - not just because they're beautiful, but because the process and every step involved in making them is incredibly thoughtful. You can be proud wearing them.

I wanted to start something in New York that focused on making products locally, and because I'd just had my second child didn't want to be traveling halfway across the world anymore. The idea was to have something wearable that fit with my reality, which was being a mom with two young kids and not always wanting to wear jeans. I still wanted to wear interesting clothes, and the options out there I found were either very expensive or very cheap. There was a big gap in the middle.

I don't follow trends - it's more of an instinct thing. Honestly, I'm kind of my own worst client. I wake up and go, "I have nothing to wear!" But that's what makes it interesting. I ask, what would make me feel good? I think it's a constant challenge because clothes are so personal. For me, my clothes are related to my mood. If I feel like I'm not wearing the right thing, I don't feel confident. I think it's in everybody's psyche.

It would be great if everybody got a conscience. If we started to take more responsibility for the pollution in the world caused by the fashion industry, and to produce less, but better-thought-out goods. Then it becomes worth saving up to buy something beautifully-designed because you can and will keep it, rather than buying a bunch of disposable fashion items you'll probably wear once before throwing away and adding to the waste stockpile. I do think people used to buy clothing with a more thoughtful approach.

For us, every day is Earth Day. It's like with Women's Day recently, I said, "Every day is women's day - we're women!" It's something that we sort of take for granted.

I've always been very aware of environment. When I was a kid I wanted to be a marine biologist until I realized I hated being underwater. I think a lot of that came from traveling and seeing the levels of waste produced by so many factories around the world.
