It's not often that three young starlets step out in the same dress, but the McQ by Alexander McQueen tartan prom dress is obviously a special case.

First worn by Emma Watson to the GQ Man of the Year Awards, it was later sported by the gorgeous Chloe Moretz to an event at the Toronto Film Festival. Most recently, Rihanna wore the dress whilst performing 'We Found Love' on X Factor on Sunday. We're not sure if all the girls are wearing the puffball version - Chloe definitely is but Emma's looks tidier around the hem, but apart from that tiny detail, they're identical.

But who wore the dress best? Chloe kept it simple with ankle booties and centre-parted hair, while Emma rocked it up with a leather jacket and pointy pumps. Rihanna went for something a bit edgier, teaming the dress with a sleeveless shirt with gold collar tips and customisable Ashish creepers, which got her in trouble when someone spotted a curse word scrawled on the side - really, who was looking that close?

Who wins this fashion face-off for you?
