"When it comes to Couture Chaos, this Tacky Terror should take a bow — looks like an over-the-hill Lolita," Mr. Blackwell said in a statement released Tuesday.
Bohemian teen tycoon Mary-Kate Olsen was the next target of the acid-tongued fashion critic. He called her clothes "bag lady rags" and "depressingly decayed."
Jessica Simpson followed Olsen. Though her Daisy Dukes shorts landed her on the pages of numerous magazines, Mr. Blackwell said she "resembles a cut-rate Rapunzel — slingin' hash in a Vegas diner."
The other offenders on Blackwell's list of fashion flops were Eva Longoria, Mariah Carey, Paris Hilton, Lindsay Lohan, Shakira, Anna Nicole Smith and Renee Zellweger.
Blackwell said Hilton — who topped his list two years ago — "still looks like yesterday's cheesecake ... with a side of kitsch."
Lohan is "drowning in grown-up groaners," he said, while Zellweger looks like "a painted pumpkin on a pogo stick."
"2005 turned out to be a particularly bad year for couture chaos, wardrobe wrecks and stylistic sleaze," Blackwell said. "These woman may be fabulously talented in their respective fields, but when it comes to fashion, they resemble weary weeds in a lovely garden."
