When you find the person that you settle down with, I guess you mellow. They are taming you, aren't they? Or you're taming them.

Depending on the season, between 20 and 30 percent of my collections contain some sort of eco or sustainable element, whether it's a beautiful organic fabric or a natural dye. And obviously I don't use animal skins or fur of any kind.

I can honestly say this industry hasn't made me neurotic about my looks, except maybe my weight. I hope my clothes kind of reflect that. They're meant to make you feel good.

I didn't want to be thirtysomething and not know what I was going to do. I was quite afraid of that, there were quite a lot of aimless kids around, in that 'other' side of my life, who didn't really know what to do because they always had a bank balance to fall back on and they were quite lost.

I don't know, maybe I'm overly paranoid that they're going to be spoiled, but I want to keep them going as kids for as long as I can. I want to keep them innocent and free.

I feel like a different person since my mum passed away, like I'm driving a ship with my husband alongside me and we're leading these four children into unknown waters.

I literally have meetings at eight o'clock in the morning, and I finish at nine o'clock at night. It sounds pathetic, but I don't even have time to go shopping.

I think the moment that I'm very proud of is building a business without using animals. And, hopefully, changing people's perception of how you can do luxury fashion.

I'm incredibly sad that my mother's not here to see my kids and that my kids don't get to know her. And she didn't meet my husband. That's one of the hardest things. I don't even know how to put that into words.

If you try to create something people enjoy, and it happens to be made in a responsible way, then that's when you can really strike an incredible balance.

It's one of my biggest internal struggles - the whole schooling system in London and the fact that my kids are going to a posh school. It freaks me out.

You have to be hopeful that people will be more educated in how they buy things, and hopefully more luxury brands will start to think that way on a longer-term basis.

Sometimes I wish I were less sensible.

You feel like everyone hates you if you've got a good life, now I feel maybe it's allowed because I've had my share of sadness.

I am a fashion designer. I'm not an environmentalist. When I get up in the morning, number one I'm a mother and a wife, and number two I design clothes. So the main thing I need to do is create, hopefully, exquisitely beautiful, desirable objects for my customer.

I think deep down I'm spiritual, but there's nothing I practice.

It's immoral that people make money out of writing crap, but I try not to obsess about it. I don't want to spend my life being angry.

People think I'm strong, but actually I wanted to crawl away. I thought, I'm going to live in the country with my horse and I'll get a nine-to-five; I don't need this.

The beliefs I was raised with - to respect animals and to be aware of nature, to understand that we share this planet with other creatures - have had a huge impact on me.

At times I make music, but in private.

Everyone can do simple things to make a difference, and every little bit really does count.

For me, singing is the most natural thing in the world. I've grown up with it and I know I've got that gift.

I confess to being a frustrated musician.
