When in doubt, wear a suit. Look at male politicians: you see them in a suit, and they look fine. But if you see a picture of them on the weekend or on vacation, there's a good chance they look terrible and unstylish.

I actually love the 'rappers look,' with the saggy pants and oversized clothes. It's very deliberate.

Look at someone like Steve Jobs. His look wasn't very special - black turtleneck and jeans - but he had style. He looked the same, and you knew it was him when you saw him. Plus, he was a very smart person, which is also very attractive. His style was simple, not distracting, and very strong.

The true test of a man's style is the haircut. There are some men who look good no matter how their hair is styled, whether it's trendy or not. A man can change his haircut many times, but to pull off any haircut, you have to be very chic. Like Brad Pitt.

I started wearing high heels when I first worked with Mario Testino. He is tall; I had to be at his height. And I have never stopped since then.

People might think I'm very hard, what with my black make-up, my hair over my eyes, etc. My innocence didn't always help me, but it did preserve something in me that maybe others don't have anymore. I'm inside my bubble, you could say, and thankfully so, because I don't think daily life is always great. It protects me.

I am afraid of blood, but for some reason often I put blood in my photos... I don't know why.

I love black lingerie and white shoes, and I love knives.

I mix talents and friendship, which is not very professional, but it's my way of thinking. So I love Azzedine Alaia, because I've known him for 30 years, and he's making my dresses most of the time.

Bleaching eyebrows makes me crazy.

Designers have told me that their collections are so me, but I don't always recognise it because if you ask me what my style is, I'm really not that sure.

The first Chanel jacket that I saw - that I knew was Chanel - was on TV. It was on Mrs. Kennedy - the pink one.

I'm so tired of this vision of fashion of a diva with a big ego, and you think of big dark glasses to be pretentious and keep far away from the people.

Maybe people have no idea how much work is behind a picture. It can seem very effortless, but there is a lot of work. It's exactly like doing ballet. It's hours and hours, but when you go onstage, it's just the pleasure of dancing.

Pregnancy is something that I always love. It's about hope and the future and a new baby.

Fashion is a completely international business.

I love the free spirit in London.

I love if someone invites me to a restaurant, so I don't know if that's a feminist.

You know it's very important, the role of a mother... I don't know, but it's feminism to me to love your kids.

I am not a celebrity. I work with celebrities, and it is very difficult. When a celebrity wears a dress, it's good for business, so brands fight for the red carpet. Me? I don't like it, because fashion becomes a job about dressing celebrities. And it's a bit boring.

Each morning, you dress to become a different woman. Fashion helps.

Becoming a grandmother brought me back to the things I forgot to love. Nature. Playing. Seeing animals. A new way of looking. A rejuvenation. A cycle of life - things come back to you. The details.

I like to surprise people. I try to take risks.

As my own boss, I have the opportunity to get to work with great brands like Old Navy, and I get to style some looks together that people can actually buy and afford.
