When I was creative director [at Estée Lauder], I was always being asked about my beauty must-haves. From there I had this fun idea to create a line of what was in my makeup bag. But I also love accessories, and people associate me with home, family, and beauty. As a girl, my favorite toy was my dollhouse; if I could still play with it now, I would! I used to love a well-arranged room: the furniture, the fabric, the lighting.

I think to make your home as comfortable as possible is so important. There’s something really interesting about that as a trend, that whole idea of lifestyle and being happy in your surroundings.

When children are little, they really need you in one way. When they're bigger, they need you as a friend. And balancing motherhood and career makes you both a better mother and a better businesswoman.

When I took the job as Estée Lauder's creative director, the first thing I did was go into the archives! I love taking our heritage and making it modern.

I come from an environment where the men actually say, "Is it OK if I take off my jacket?" in a meeting. Everyone wears suits; it is a very dressed-up world. Even if I wear jeans, I still wear a blazer and jewelry. I think there is something nice about coming to work and dressing nicely.

I love Pilates, I really do, and I do it three times a week because it works well for me.

I've always loved the beauty world. Ever since I was a child, I looked at magazines and wore fragrances and tried out samples and sets. I worked at Clinique in the creative department for a summer during high school. And when I graduated from university, I worked at Prescriptives. My uncle [Leonard Lauder, chairman emeritus of the Estée Lauder Companies] smartly had wanted me to go into a small brand - to figure out what part of the company I loved. I discovered I was passionate about the creative process, the product development, creating a concept around a fragrance or lipstick.
