Stella McCartney

More than anything I want to be fit so I don't get out of breath when I play football with the kids.

Designing kids clothes is something personal to me because I'm a mother. So to be able to see my kids wearing something I've designed is very fulfilling. With the kids' collection, we really try to focus on great quality with an accessible price point in styles that appeal to both parents and kids.

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.

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.

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 did always say I wanted to infiltrate from within. That was always my reasoning behind going into partnership with a luxury group that uses a lot of leather in their products.

We have captured a luxury and richness with our fur-free fur, which is proof to the fashion industry that killing animals for the sake of fashion is unnecessary.

I think my differences were, and my differences still are, that I don't really approach fashion in a fashiony way.

I think the reality is that, for me, real fur is extraordinarily old fashioned. I think you look old. Even if you're 20, and you've got a real fur coat, you just look like an old, unaware, unconscious being on the planet. It's not relevant, it's not sexy, it's not fashionable, and it's not cool.

It wasn't easy navigating publicity when I started, because I grew up with 'being famous,' and I'm just not into it, and I guess defensiveness gets read into that. And I didn't get an easy ride at the beginning.

I never want to promote an ad that makes women feel bad about themselves, because when I was young, I never felt rich enough or fashionable enough or good enough. I felt talked down to by luxury fashion labels. There was a disconnect. They made me feel we weren't right for each other.

I confess to being a frustrated musician.
