But with the Hollywood new comer fan of skinny miniskirt Victoria “Posh” Beckham named the worst dressed on Blackwell's annual best and worst list.
Blackwell, an 85-year-old Los Angeles-based former fashion designer, first released his Ten Worst Dressed Women List in 1960, with Queen Elizabeth II, Martha Stewart and Dolly Parton past alumni.
"Forget the fashion spice - wearing a skirt would suffice," Blackwell said in announcing his list.
"In one skinny-mini monstrosity after another, pouty Posh can really wreck-em."
Beckham edged out another Brit for the unwanted honour, the drug-troubled, tattooed eyeliner-lover, Amy Winehouse, who was named second worst-dressed woman.
"Exploding beehives above, tacky polka-dots below ... she's part 50's car-hop horror," was how Blackwell summed up Winehouse.
Third on the worst-dressed list was former wonder twin, Mary Kate Olsen, whose style was described as resembling "a tattered toothpick-trapped in a hurricane" and fourth was another songstress, Fergie, who Blackwell said was "couture chaos".
Rounding out the worst top 10 was fifth placed Kelly Clarkson, derided for her "belly-baring bombs", then French Bond girl Eva Green ("Stuck in neon nightmares"), followed by Avril Lavigne ("Gothic make-up courtesy the mad spatula"), Jessica Simpson ("She's a global fashion curse"), Lindsay Lohan ("Fashion frenzy strikes again") and in 10th, former Little House on the Prairie bad girl Alison Arngrim ("Looks like a 1940's fashion editor for the Farmers Almanac").
Last year Britney Spears ("Style-free and fashion deprived") was named worst-dressed, beating out Camilla Parker-Bowles who Blackwell described as resembling a "parakeet from the Jurassic age".
Joining Kidman, Blanchett, Witherspoon, Khan and Jolie on this year's best-dressed list were Beyonce, Helen Mirren, Katie Holmes, Katherine Heigl and Prince William's on-again, off-again girlfriend, Kate Middleton.
