Salma Hayek vs Emma Bunton

We can't get enough of this purple Alexander McQueen sheath. Ever since Emma Bunton stepped out in it last month for the Commercial Radio Awards we've been hooked on the chic pleated frock.

So we couldn't blame Salma Hayek for copying the former Spice Girl when she turned up to The Late Show in an identical dress.

Both ladies have nailed the effortless glamorous look. Emma kept things classic by teaming the dress with a pair of black court heels while Salma opted to go nude, with matching shoes and bangle.

But whilst we could talk about our love for this dress all day long, there is one thing we need to get to the bottom of... who wore it best?
