The latest installment of Defamer's last-minute Halloween costume guide features an idea we guarantee you ladies will have all to yourselves come Friday night. Lucky you: This sultry get-up is in fact one of the hottest looks of the fall movie season, yet hiding in plain sight among action aficionados who will flock to see it next month at the multiplex. Don't let the opportunity pass you by, though — follow the jump to see how a cheap frock and a few other inexpensively obtained features can make you this year's overnight sensation.

You are (formerly) 12-fingered Bond girl Gemma Arterton! For added fun, accessorize with some delicious marzipan finger candy and have your 007 of choice gnaw off each extra digit at key points in the evening — preferably whenever accosted by pals beckoning "Trick or treat!" Why not both?
