Mr Blackwell's Worst Dressed in 2007

He started in 1960, and again this year he comes up with the goods. Mr Blackwell's Worst Dressed 2007 list came out yesterday, and Victoria Beckham topped the list of horribly dressed stars last year. "In one skinny-mini monstrosity after another, pouty 'Posh' can really wreck-em," said Blackwell of one half of 2007's most powerful supercouple.

Number two on the list was singer Amy Winehouse with her "Exploding beehives above...tacky polka-dots below...she's part 50's car-hop horror." Mary Kate Olsen polled at number three, with Blackwell saying of the actress "YIKES! In layers of cut-rate kitsch, Mary Kate's look is hard to explain...she resembles a tattered toothpick-trapped in a hurricane." And former Duchess of York, Sarah Ferguson got a dig too, when Blackwell described number four, singer Fergie: "Another style-free 'Fergie' in fashion's hall of shame? Yes, when it comes to couture chaos, guess it's all in a name." Also featuring on the list are American Idol winner Kelly Clarkson, actress Eva Green, Canadian rocker Avril Lavigne, hehe Jessica "Yall" Simpson and train wreck Lindsay Lohan.
