Mary-Kate Olsen appears on 3 covers for the Marie Claire US September 2010 issue.

I’m not a fan of multiple covers, because the cover I want is never available in my newsagent.

My favourite is the Pucci cover. Mostly because of the stunning dress, but also because she’s teasing us with a rare smile.

On the other covers which – were shot by Tesh MK wears a military Burberry Prorsum coat and a sequined Gucci dress with feathered sleeves.

The young designer talks to Marie Claire about talks about her fast-paced lifestyle, running a fashion house in New York City, The Row, her passion for clothing, losing her friend Heath Ledger and how she feels about having been a child actor.

You can read more at MarieClaire.com. Here are some extracts.

On loving her fashion lines: “It’s kind of like a mask to hide behind.”

On her childhood: [She and her sister were like] “little monkey performers.”

On her childhood memories: “I look at old photos of me, and I don’t feel connected to them at all… I would never wish my upbringing on anyone…”

On learning to seek professional help when she needs it: “I think it’s really important to be able to talk when something’s wrong. I learned at a really young age that if you don’t talk about it, it can drive you insane.”
