The Italian designer has created two special looks for the American singer's Prismatic World Tour which kicks off this week.
Katy Perry will hit the stage this week wearing two Roberto Cavalli looks created especially for her by the Italian luxury brand.
They are certainly designed to keep all eyes fixed on the 29-year-old singer: the 'Kaleidoscope Brodè' dress is embroidered with prism crystals, sequins and iridescent micro baguettes. The dress's holographic mirror effect is created by a tulle plastron and patchwork leather motifs to create 3D reflections.
The second look, a 'Crocodile Scarab' silhouette features a pleated skirt and a micro top in mirrored multicolor leather. There's a crocodile graphic on a multilayer light mousseline silk lamé, covered with a thin layer of silver powder for added shine, and a printed leather biker jacket is worn over the top with a holographic reptile motif.
It's the latest in a series of music and fashion collaborations which have seen Calvin Klein create special stage looks for Drake, Maison Martin Margiela dress Kanye West, and Roberto Cavalli design custom gowns for Beyoncé's Mrs Carter tour.
The Prismatic tour begins this Wednesday (May 7) in Belfast, Northern Ireland. Perry will also wear an haute couture gown by Valentino, which she revealed via Instagram last week.
