Rachel McAdams Wows In Marchesa At 'Sherlock Holmes' Premiere (PHOTOS)

Rachel, it's been awhile.

The actress has been lying low lately -- we haven't really seen her out since she was Occupying Wall Street in Toronto last month -- but we're glad she made it to the "Sherlock Holmes: Game of Shadows" premiere in Los Angeles last night,

Bedecked in a shimmery Marchesa Resort 2012 silver gown, Rachel looked ready to solve a really glamorous crime with her long train. She also wore Jacqueline Nerguizian jewelry and sparkly Louboutin booties (an interesting choice).

We're also loving her beauty picks: light makeup with a hint of pink gloss and a chic updo.

And her sartorial choice was true to form: Rachel usually opts for simple elegant on the red carpet, like this white Louis Vuitton gown and her tan trousers from Cannes this year.

But it seems Rachel had a style twin: Swedish actress Noomi Rapace was wearing a strikingly similar Valentino gown on the red carpet. Maybe the ladies could have benefitted from a pre-premiere conference call?
