Olivier Rousteing's Balmain created 16 custom outfits for Beyoncé's Renaissance World Tour, each inspired by a song from the album. The 'Alien Superstar' crystal gown and 'I'm That Girl' hammered metal bustier represent the highest tier of musician × designer collaboration: sculpture meets fashion meets music. These are one-of-a-kind haute couture pieces that rarely, if ever, appear on resale.
