Fifty Shades of Grey is one of the raunchiest books of the century so its no surprise the world premiere of the hotly anticipated film adaptation had fans whipped into frenzy. Just like the book itself the red carpet was a very sexy affair. Leading lady Dakota Johnson took her sartorial inspiration from the dark romance of the story in a black plunge neck Dior gown that showed off her slender figure. While her handsome co-star Jamie Dornan, aka Mr Grey, looked suitably dashing in a black suit, which he teamed with a navy bow tie and matching pocket square.
