Victoria Beckham not so "Posh" in '07

LOS ANGELES (Reuters) - She crossed the Atlantic to hit the big time in fashion, but on Tuesday Spice Girl Victoria "Posh" Beckham suffered her first Hollywood flop when style maven Mr. Blackwell named her the worst-dressed celebrity of 2007.

"In one skinny-mini monstrosity after another, pouty 'Posh' can really wreck-em," Blackwell said in his annual list of fashion fiascos among music, movie and television stars.

With husband and soccer star David Beckham, she moved to Los Angeles last year amid huge media fanfare, and among the top items on Posh's "to do" list was launching herself as a style setter with a passion for fashion.

Beckham, who has been on a reunion tour with the Spice Girls, was not alone among pop stars who earned Blackwell's disdain.

In the No. 2 spot was singer Amy Winehouse with tough-girl tattoos, mini-skirts and hair piled high. "Exploding beehives above, tacky polka-dots below," said Blackwell.

Just behind was former child star Mary-Kate Olsen whose diminutive frame and floppy fashion "is hard to explain," said Blackwell. "She resembles a tattered toothpick trapped in a hurricane," he said.

Blackwell has issued his "Worst-Dressed" list for 48 years, and for just as long it has been widely watched and talked about among fashion followers. He began his career in the 1950s, had his own clothing line for 35 years and designed for older stars Jayne Mansfield, Peggy Lee and Jane Russell.

He said this past year stands out as one of the "most disastrous fashion years in recent memory."

Singers seemed to hold a key spot in Blackwell's mind in 2007 with pop stars Fergie and Kelly Clarkson as No. 4 and No. 5 in the worst-dressed rankings.

But amid all the fashion faux pas, Blackwell was able to find some stars who managed to look good, including Madonna, Barbra Streisand, Elizabeth Taylor and even the Queen who, Blackwell said, "managed to update her Stonehenge of Style image."

The 2007 top 10 worst-dressed list is as follows:

1. Victoria Beckham

2. Amy Winehouse

3. Mary Kate Olsen

4. Fergie

5. Kelly Clarkson

6. Eva Green

7. Avril Lavigne

8. Jessica Simpson

9. Lindsay Lohan

10. Alison Arngrim
