Cheryl Cole’s devotion to shopping has finally paid dividends after she scooped two style awards.

The Girls Aloud singer and X Factor judge was voted best dressed woman of the year and style icon of the decade in a survey of more than 3,000 women, aged 20-60, for TV channel The Style Network.

The wife of Chelsea star Ashley Cole beat stiff political competition in the shape of US First Lady Michelle Obama and French President’s wife Carla Bruni to scoop the style icon accolade.

The survey also revealed that women were seen as at their most stylish when aged between 25 and 30. And 56 per cent of those in their 20s who were quizzed spent more than a quarter of their income on clothes and cosmetics.

Other fashion secrets revealed were that the average British woman bought 20 pairs of shoes each year.

Cheryl beat model Kate Moss to top spot in the Best Dressed Women List 2009 by Glamour magazine.

Jo Elvin, editor of Glamour, said: “In the past year, Cheryl Cole has become everyone’s style crush. She’s ridiculously gorgeous, beautifully groomed and always glossy, glossy, glossy.”

But it was a bad day for former glamour model Katie Price who was voted worst dressed woman of 2009.
