The gorgeous actress stunned at a private event for the Alexander McQueen: Savage Beauty exhibition in London, England on Thursday.
The "Once Upon a Time in Mexico" star looked breathtaking in a black lace, peacock-inspired gown. The brunette beauty styled her hair in bouncy pinned-back curls and completed her look with strappy sandals and a matching clutch.
The vintage look (and most likely a corset) also accented Salma's super cinched waist -- can you believe how tiny the actress looks?!
Hayek wasn't the only star to steal the spotlight -- Robert Pattinson's girlfriend/singer FKA Twigs wowed in her rainbow colored dress, which even came complete with matching feather wings.
The UK native finished her look with a bold red lip and styled her dark brown tresses slicked-back and parted down the center. That's a lot of look!
Meanwhile, Victoria Beckham hit the red carpet with husband David Beckham look rather ghostly as they posed for pictures.
