In the first list of its kind compiled by Vogue, the supermodel was judged to have had more influence than any other model or celebrity on the way other women dress.
"At every moment Kate Moss has looked chic and cool," the Daily Mail quoted Vogue style director Alexandra Kotur as saying.
"We chose people who were thinking out of the box, women who look as if they're wearing what they really wanted to wear.
"The whole Vogue editorial team and fashion staff brainstormed to come up with the list.
"Our parameters were to highlight from the year, and the overarching theme that we observed was to recognise an emphasis on the individual.
"No one has had more influence for the past decade on the way women have dressed than Kate Moss," Kotur added.
In a supplement, the magazine has named 11 of the world''s most sartorially stylish celebrities.
And it has given them each a title, representing glamour to urban style and raw individuality.
Lady Gaga was named as most 'visionary' for her astonishing array of bizarre outfits, whilst First Lady Michelle Obama was named the most independent.
