The Dixie Chicks were included on Mr. Blackwell’s 40th annual worst-dressed women list. “They look like a trio of truckstop fashion tragedies trapped in a typhoon,” he said. The list also dressed down Celine Dion, Queen Elizabeth, Martha Stewart, Fiona Apple, Britney Spears, Sarah Jessica Parker, Jennifer Aniston and Cameron Diaz. Cher topped the list. Blackwell is a former fashion designer who writes a column for a supermarket tabloid.
