The '70s were full of creativity. Everybody was so unique. It was a very creative period, and I think to be a designer you have to know a little about art and literature and music because there is inspiration in all of these things. You're looking for beauty but also something that makes sense.

Unfortunately, there's a lot of confusion today over what is sexy and what is vulgar. It's horrifying. They say, 'Oh, that girl is so sexy,' and she turns around and the dress is four sizes too small. Or she's wearing so much stuff, you wonder how long it took her to get ready.

I don't like trends. They tend to make everybody look the same.

The first painting that I realised I liked was 'The Garden of Earthly Delights' by Hieronymus Bosch, when I was six years old, at the Prado in Madrid. I still find myself returning there every time I'm in the city.

I didn't long to be a designer. I always liked fashion, but it was always a bit sleeping in me.

One thing about my mother is that she has her taste: She knows what she likes and what looks good. It's not studied. There is no insecurity in what she is going to wear, and I think that translates into effortlessness. Her career has been a steady rise, and it hasn't been about the fashion of the moment. It's been because she has kept to her style. She didn't go grunge when it was grunge, or 70's when it was 70's. It's about being secure with what you like and not worrying about what's in fashion that particular day. That's what I admire about her.

Queen Elizabeth of England is the real fashion icon of the century. And she has a sense of humor.
