Why Did Beyoncé Change Outfits Four Times in One Night?

Saturday night's Sound of Change fundraiser concert—hosted by Chime for Change, a charity focused on education, heath and justice for women around the world—in London had all the trappings of a buzzworthy event: star power (Jessica Chastain, Blake Lively and Freida Pinto were all in attendance), memorable musical acts (performers included Florence Welch, Jennifer Lopez and Ellie Goulding) and great fashion (mostly by way of Gucci, who sponsored the event). But out of every single guest and performer, no one delivered the same level of star power, memorable music and great fashion that Beyoncé Knowles did.

As both a co-founder of the Chime for Change initiative (along with Gucci creative director Frida Giannini and actress/former Lucky cover girl Salma Hayek Pinault) and the creative director of the evening's festivities, Queen B gave the evening her all with a 45-minute-long set complete with four outfit changes. While most of the outfits were for performance purposes, we still want them all for our non-superstar-married-to-Jay-Z lives. (With a few styling tweaks, of course.)
