Jessica Alba  may have been the belle of the red carpet at last night's LA premiere of Sin City: A Dame to Kill For (in case anyone's wondering, she's the dame), but her two supporting stars Jaime King and Jamie Chung came out in full fashion force. Sure, it was hard not to take your eyes off Alba's electric-blue strapless Zac Posen  dress — which she paired with diamond Chopard  rings and a Lee Savage cracked silver clutch — but pal King gave her some stiff competition in a long black Versace  dress with a bold neckline. We even loved how her asymmetrical black suede mules by Monique Lhuillier  followed suit! But then there was Chung, who wowed in a velvety plum Pamella Roland  cutout gown.
The dresses, just as bold from the back as they are from the front, are definitely enviable, but which would would you commit a fashion-related crime to get in your closet? See all angles, and then vote below.
