And you'll never guess who opted to wear nothing underneath it... 

Indeed, some time ago, Salma Hayek wore this coveted Gucci lace dress during an appearance on Jimmy Kimmel...

Julia Roberts sported it while she was addressing the crowd at the InStyle Awards back in October... But it had to take Rihanna wearing it with nothing but a pair of black pants underneath it while roaming around NYC on Wednesday night to get people talking about it. Well, 'naked' dresses are all the rage.

Who wore it best? Salma, of course. Black lace is always best (unless you're talking about the band... although you can't beat a bit of Agadoo...)
