Who? Isla Fisher
What? There was a chilly breeze a'blowing last night, but you wouldn't have known it from the barely-there dresses that were out in force at the world premiere of Les Miserables. First, leading lady Anne Hathaway stepped out in a beautiful backless gown by Givenchy, then Amanda Seyfried braved the cold in a plunging Balenciaga number.
Next up to flash some flesh was Isla, who dared to bare in an white cut-out dress by Willow.
Where? London
Verdict? There's no doubt Miss Fisher looked stunning, and we loved those sparkly-heeled Christian Louboutin shoes, but hold on just a second, where's the groom?
It's difficult to wear a flowing white frock and avoid looking like a bride, and we're not sure Isla got away scot-free. What do you reckon, ethereal elegance or here comes the bride?
