Yui Mok/PA WireSome cold, windy weather didn’t stop Iron Man 3 star Rebecca Hall from wearing a revealing outfit at the film’s London premiere today.
The brunette beauty stole the show in her daring Lanvin jumpsuit that revealed, well, a ton of cleavage and a flash of side boob.
Hall topped the sexy ensemble off with slick pulled-back hair and a bold red lip.
Robert Downey Jr.’s co-star took center stage as she stunned the crowd with her ample décolletage.
Hollywood can’t get enough of the side boob trend!
