Alison Goldfrapp
Cate Blanchett
Worst
Basically all the hip Hollywood sticks, clones and people toting the Balenciaga Motorcycle bag. Britney, Tara Reid, Lil Kim, Christina Aguilera and co. The OC crew and their gang. Cher. Melanie Griffith. Tyra Banks. Victoria Beckham.
It's too hard to write a list about the worst star styles, it's VERY hard to find even five good ones! 99 % of the current stars don't dress well in my opinion.
Btw, my list was of 'new' people, not the old Hollywood or deceased.
