Everyone should take a leaf out of Storm's book. Don't be hemmed in by the 'black tie' label - you can always be gown from the waist up, and black (or navy, for the pedants among you) tie from the waist down.

Those who strictly stuck to the dress code, including Ronan, were the film's stars Lea Seydoux, Daniel Craig, Monica Bellucci...

And - of course - the Duke and Duchess of Cambridge were suited and booted to the max. Admittedly we're inlove Kate's dreamy dress, particularly how it melds into a sheer cape at the back. Needless to say, it's Jenny Packham.

Those who also embraced the glitz of the occasion include Joely Richardson, Naomi Harris, Amber Le Bon, Susanna Reid, Stephanie Sigman...


 
And, of course, Joan Collins...

Kudos to Sam Smith who managed to look dapper while grappling with his shoe laces...
