Kate Moss dresses down

Kate Moss never "dresses up".

The 37-year-old supermodel is regarded as one of the world's most stylish women and says one of the secrets behind her classic and simple style is that she never follows trends and only wears clothes she feels comfortable in.

She said: "I never 'dress up'. I wear things that I like and that are my style. That might seem very simple, or even simplistic, but it's the complete truth. This harmony between my inner self and my look is perhaps what appeals to so many people."

Another secret to Kate's flawless look is to smile as she says everyone looks better when they do.

She told Britain's Grazia magazine: "True beauty is laughter - everyone looks beautiful when they are smiling."

Kate recently became the face of new Dior fragrance, Dior Addict, and says Dior is a brand she's always been a fan of.

She said: "Since starting out in the fashion industry I've been close to the House of Dior and particularly to John Galliano. Our long friendship is built on mutual admiration and loyalty to each other. Dior has such a luxurious and feminine image."
