PHOTOS: The Best, Worst & Wackiest Fashions Of The Weekend

From the red carpet to the streets, stars were out and about over the weekend dressed in the best, worst & wackiest fashions -- and RadarOnline.com has all the photos in our weekend roundup.

Elisabeth Moss scored the best look of the weekend, hitting the 2011 Olivier Awards in London looking Grecian gorgeous!  Draping her bod in a nude Donna Karan gown, the Mad Men star, who is currently starring alongside Keira Knightley in The Children’s Hour play, finished the look off with a metallic Jimmy Choo clutch.

Fergie sported shredded threads to DB Donamatrix’s New Fitness Regimen Launch Party in West Hollywood.  Her Balmain blunder included stripped pants, a ripped up shirt and studded leather jacket.

And leave it to Lil’ Kim to up the wacky factor.  The sassy mouthed rapper was dressed for a Halloween party at The Luxxx Ball in NYC, palling around with the Damon, who looked equally as bizarre in a metallic tracksuit.

Teresa Palmer looked white hot in a short-trained Cushnie et Ochs mini dress at the Paris premiere of I Am Number Four, while Emmanuelle Chriqui slithered down the red carpet in sexy style at the Vegas Magazine Spring Fashion Issue party in Sin City, wearing a python print Roberto Cavalli gown.

Zoe Saldana looked charitably chic and perfectly put together at the John Varvatos 8th Annual Stuart House Benefit, wearing a tight leather jacket with Decades Denim skinny jeans, leopard heels and a Diane von Furstenberg metallic hobo, while Gina Gershon experienced a fashion flop wearing sneakers on the carpet.
