Washington, Nov 17: Pop star Christina Aguilera will wear designer Roberto Cavalli's glamorous costumes during her Back To Basics world tour.

The Dirrty singer has hired Cavalli - known for his splashy stage costumes - to exclusively design the elaborate outfits based on the 'circus' theme for the tour.

Sources claim that the fashion mogul has already created 10 costumes for Aguilera, and is also commissioned to create looks for her dancers, reports Contactmusic.

And according to Women's Wear Daily, some of the outfits include a Forties-style white stretch satin tuxedo, bordered with golden pearls and topped with a white fox stole; a Fifties-inspired satin silk bustier and printed, gold-leaf and crystal-adorned silk taffeta skirt; a Sixties suit embroidered all over, and a tailored jacket with embroidered tails to be paired with a red-and-black Swarovski-adorned bustier.

Christina's world tour will start in the US in February (07).(ANI)
