Posh Spice Victoria Beckham has topped Mr. Blackwell's 48th annual worst-dress list.
"Forget the fashion spice, wearing a skirt would suffice! In one skinny-mini monstrosity after another, pouty Posh can really wreck-em," Blackwell said in a statement.
Amy Winehouse was named the second-greatest fashion mess, with Blackwell saying: "Exploding beehives above, tacky polka-dots below, she's part '50s carhop horror."
Mary-Kate Olsen took the number three spot, with Blackwell saying: "She resembles a tattered toothpick — trapped in a hurricane."
Fergie, Kelly Clarkson, Eva Green, Avril Lavigne, Jessica Simpson, Lindsay Lohan and Alison Arngrim made up the rest of the top ten fashion disasters.
Britney Spears, who has featured in the list many times, was missing from this year's list.
"I felt that it was inappropriate at this time to make comment, when her personal life is in such upheaval. I hope 2008 is a better year for her," Blackwell said.
