Emma Burton, aka Baby Spice, and Salma Hayek recently rocked the same purple Alexander McQueen Pre-Fall 2010. Emma wore it first while attending the Arqiva Commercial Radio Awards in London last week and paired the dress with a pair of black Christian Louboutin heels. Salma wore her dress earlier this week with a pair of YSL Trib Too pumps to the taping of the Late Show with David Letterman in New York. Who rocks the McQueen dress better?
