Supermodel Kate Moss has topped Grazia magazine's best-dressed list for the second year running - but she's facing competition from newcomer Lily Allen.

Allen's trademark look of trainers and prom dresses has proved a hit with fashionistas.

She is a new entry in the list at number 10. The daughter of actor Keith Allen is rumoured to be lined up as the new face of fashion house Chanel.

"Lily Allen is a real one-off. Prom dresses and plimsolls, chav bling and a fat fringe, crazy-colour catwalk make-up - we haven't seen a girl having this much fun with fashion since Kelly Osbourne," Grazia said.

"Allen's urban edge makes her the ultimate style icon for the Myspace generation. Cool, talented, successful, and with more attitude than Vicky Pollard, at 21, Lily Allen is already her own woman."

Moss is still the undisputed queen of fashion, topping the list voted by the readers.

"Sometimes quirky, often unpredictable but always cool, Kate does whatever she likes," the magazine said.

"But she's still making us wait for the one outfit we all want to see - the wedding dress."

The OC's Mischa Barton is in second place, followed by Kylie Minogue. The magazine hailed Kylie's transformation from pop princess to the epitome of Parisian chic since moving to the French capital with boyfriend Olivier Martinez.

Curvy actress Scarlett Johansson is fourth. "In an industry obsessed with size O and the debate around it, we really needed a sexy superheroine to save us from thinking we have to starve ourselves to be beautiful - and we got one," Grazia said.

Party girl Lindsay Lohan is fifth, ahead of singer Christina Aguilera and Marks and Spencer model Erin O'Connor.

Victoria Beckham is up from 10th place last year to eighth this year.

The magazine awarded her their Transformation of the Year honour after she ditched the "WAG" hair extensions and false nails for high fashion.

But there is bad news for Sienna Miller, who has slipped from second to ninth place since 2005.

Grazia editor Jane Bruton said: "Our readers voted mostly for those women in the public eye who embrace their own distinctive, individual style.

"The biggest accolade must be given to Kate Moss - whatever the speculation about her private life, she remains the enigmatic style icon of our times."
