10.) Alison Arngrim: “Little Nellie of the prairie, looks like a 1940′s fashion editor for the Farmers Almanac.”

9.) Lindsay Lohan: “Lindsay the fashion frenzy strikes again! Lohan takes fashion to a new low.”

8.) Jessica Simpson: “Forget the Cowboys. In prom queen screams, can it get any worse? She’s a global fashion curse!”

7.) Avril Lavigne: “Gothic make-up courtesy the mad spatula-Fashions provided by.. The house of Dracula!”

6.) Eva Green: “Stuck in neon nightmares not fit for the sane. Fashion this loud could give Bond a migraine! A profusion of confusion from toes to nose!”

5.) Kelly Clarkson: “Her heavenly voice soars above the rest… but those belly-baring bombs are hellish at best! She may be the queen of ‘Pro-Active’ – but that wardrobe looks downright radioactive!”

4.) 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!”

3.) Mary Kate Olsen: “YIKES! In layers of cut-rate kitsch, Mary Kate’s look is hard to explain… she resembles a tattered toothpick-trapped in a hurricane!”

2.) Amy Winehouse: “Exploding beehives above…tacky polka-dots below… she’s part 50′s car-hop horror.”

1.) Victoria Beckham: “Forget the fashion spice – wearing a skirt would suffice! In one skinny-mini monstrosity after another, pouty posh can really wreck-em.”

Britney Spears — Us’ worst dressed star of the year — was left off.

Mr. Blackwell added a note at the end of his list:

“For those of you who were expecting to see Britney’s name adorn the 2007 list, I felt that it was in appropriate at this time to make comment, when her personal life is in such upheaval. I hope 2008 is a better year for her.”

Some celebrities making the best-dressed list were, Reese Witherspoon, Nicole Kidman, Angelina Jolie, Katie Holmes, Beyonce, Helen Mirren, and Katherine Heigl, among others.

Poor Jennifer Aniston… she doesn’t even make lists anymore.
