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.
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.
I grew up on an organic farm in England. And I was a vegetarian from an early age - not just for health, not for the environment - just because I didn't believe in killing animals to eat them.
I'm a woman designing for women, and there are so many layers to that. On the one hand, it brings an effortlessness, but it also means that I think and overthink every detail, whether it's physical or mental or even - in some sense - spiritual.
I like doing slightly masculine, Savile Row tailoring. A nice jacket. Wearable - it's almost a dirty word in fashion, wearable, but that's what I do.
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 important for us as a family to go and sit in the woods sometimes.
I can debate for weeks whether a trouser should sit on the waist, or a centimetre below, or on the hip, whether it should have a zip or a button, because I find personally that a detail like that can have a massive impact on how I carry myself that day. If I wear a slouchy jean, that will affect my posture and my whole manner.
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.
My mum had a massive influence on me, not just in what she wore and how she looked, but in her spirit. She was married to one of the most famous men in the world, and she didn't wear any makeup, ever. I mean, have you ever seen the wife of a man like that rock up with no makeup on? Because I haven't since.
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 think my differences were, and my differences still are, that I don't really approach fashion in a fashiony way.
The way my parents brought me up to see the world is still absolutely key to what I am about. 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.
Sustainability goes across everything I do with Adidas and everything I do with my own house, so the Olympic kit is no exception. It is incredibly environmental in the way that it is manufactured. For example, there's no leather; it's free from PVC. There's lots of woven materials, which means a lot less waste.
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 guess my favourite Disney film was 'Snow White,' which has a really dark moment when the evil queen turns into a witch and makes the poison apple. It was terrifying in the same way 'Maleficent' is.
Ninety percent of the people who come to my stores have no idea I don't work with leather.
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.
My job is to make desirable, luxurious, beautiful clothing and accessories women want to buy. My first decision is always based on, 'Can I do this in a more sustainable way without sacrificing design?' If I can, then there is no reason not to.
