I'm used to spending a lot of time with my team. They're not only collaborators, they're also friends. It's the biggest part of your life that you share with these people. But sometimes being on the top of this pyramid, you need to be a little bit tough. This job is becoming very tough for every company because of timing. You don't have the time to finish the collection before you have to think about the next one. But I am never loud. I don't like to scream. So we are all working hard, and sometimes you need to reassure them.

The first thing I notice about a man are his shoes. Then I look at his watch.

When I approach a collection, I never think too much about myself, because doing fashion and being a designer, you need to dream. Of course, there's always a part of myself. I'm always wearing what I'm doing. I'm not a party girl, but when I have the opportunity to go out and dance and be crazy for a night, that's the fall/winter collection.

I always loved the look of musicians. I've always admired them because they have a look - when I was growing up, it seemed that the ones I liked didn't need to have a stylist. Now there is this trend where everyone has a stylist, or follows the suggestions of a stylist, from designers on down.

I inherited this collection of vinyl records, which at that time numbered 6,000, and I've since continued to collect music. As you know, vinyl records can be very heavy, so every time I have to move into a new house, I need to build a complete new wall of shelves to put all these records, which is a nightmare for the architect.

I always had a very strong sense of responsibility, so the minute I started to work in fashion, I was always tremendously serious-too much sometimes. Of course, you can make a lot of mistakes in this job-I still do-but you need to limit them as much as possible. When you're responsible for such a huge company, you cannot play too much. In the beginning, I was working 20 hours per day and I was going crazy. I learned that I needed to delegate and to trust the people around me, but there is still not one element that I don't see or edit or discuss with my people.

All the drawings and sketches and clothes of Yves Saint Laurent in the '70s were so colorful, so bright.
