You know that moment when you curse the Gods of Mass Produced Style - you've spent hours getting ready and you've tried on at least 293 different dresses. You think you've finally nailed it, creating an outfit that combines the elegance of Audrey Hepburn with the swagger of Béyonce.
And then you spot her. The girl at the next table is wearing YOUR outfit. There's a moment of panic and disappointment, quickly followed by a series of furtive glances to establish if she making you look like Quasimodo.
Now imagine if instead of it being Gobnait from the post office wearing the same dress, it was someone like Cherridle Cole. Ah, who'd be a celebrity?
But different hemlines, a customising touch and an accessory or two can change the look of an outfit.
So let the battle commence! Who do you think wore it best and why? Has it ever happened to you? And can anyone EVER top Helen Mirren?
