Thierry Mugler will be costuming Beyonce's tour. "In addition to serving as 'creative adviser,' with input on everything from set lighting to choreography, Mugler will direct three segments of the show, called 'Dangerously in Love,' 'Ave Maria' and the finale. Hell also costume the production from the star herself, who will wear approximately 58 Mugler creations, to the band, back-up dancers and singers." via WWD

Personally, I would love to see her in the above outfit...
