BEST: Actress Jaime King was a real Pretty Woman at the Veuve Clicquot Polo Classic at Will Rogers State Park on Sunday. With her hair loosely tucked under and wearing a satin-skirted peach dress with ruffled bodice and gladiator heels, the Sin City star’s sophisticated style was perfect for stomping the divots.

WORST: It was a double disaster when Paris Hilton and Petra Eccleston hit the town together on Sunday night in matching leopard print outfits. With Paris wearing a green floating dress and Petra pairing her bustier with leather trousers, the pair was clearly on the prowl in Los Angeles but all they hunted down was Greasy Bear Brandon Davis.

BEST: Married life seems to be suiting Kate Moss’ style as the supermodel stepped out in a sparkly shift dress and simple black pumps at Sir Paul McCartney and Nancy Shevell’s wedding in St. John’s Wood on Sunday.

WORST: Considering that she runs her own fashion empire, you would think that Kim Kardashian would know how to dress for her unique body type. The reality star’s famous butt looked larger than ever in black pants that clung in all the wrong places and a floaty silver shirt when she and Kris Humphries went to see pal Lala Anthony in an off-Broadway play.

BEST: She has been wowing fans in her flawless Marilyn Monroe costumes to play the film icon, but Michelle Williams was just as stunning as herself when she appeared at the 49th Annual New York Film Festival premiere of My Week With Marilyn on Sunday in a delicate ethereal dress with plunging neckline.

WORST: Doesn’t Phoebe Price know that pandas and zebras aren’t even from the same continent, and certainly not native to California! The wanna-be star paired a panda hat with a zebra-striped dress to combine for the most inappropriate outfit of the day at the Mr. Bones Pumpkin Patch on Sunday.

BEST: Dressed in a Jason Wu dress, Avatar star Zoe Saldano made the most of the last days of summer at the Veuve Clicquot Polo Classic at Will Rogers State Park in the Pacific Palisades with champagne, sun and hot polo players!

WORST: With her steel grey suit, stern expression and tightly-tied back hair, Gina Gershon looked like she was ready to interrogate someone at the 49th Annual New York Film Festival premiere of My Week With Marilyn on Sunday. Even bright red lips can’t soften this startling sight.

BEST: It’s hard to stand out among fabulously dressed drag queens but Vanessa Williams held her own at Best in Drag at the Orpheum in Los Angeles in a silver dress that showed off both her amazing cleavage and slim legs.

WORST: Is Erin Wasson turning from modeling to circus performing? That is the only excuse she can have for wearing baggy clown pants and a leather bra top to the 49th Annual New York Film Festival premiere of My Week With Marilyn on Sunday. We expected her to be swinging onto the red carpet from a trapeze in that ridiculous get up.

BEST: Sir Paul McCartney looked like the cat the cream at his wedding to Nancy Shevell at Marylebone Town Hall London on Saturday. The bride wore a white Stella McCartney shift dress, and the groom wore a very happy grin!

WORST: No worst dressed list would be complete without Lady Gaga, who didn’t disappoint in a black and fuchsia micro mini, sky-high purple heels and patterned head scarf as she strutted through New York City. While her outfit would definitely stop traffic, it was the Bad Romance singer’s teal lipstick that really caught everyone’s attention.
