Flashback to the '90s!

Designer ROBERTO CAVALLI, whose limited collection literally flew out of H&M stores earlier this month, is designing the costumes for his pal VICTORIA BECKHAM and the rest of the SPICE GIRLS' world tour, and ET has a sneak peek at the new sketches from OK! magazine, in its new issue on stands Friday.

"I have known Victoria for a long time, and have always admired her style and personality," he says. "When we talked about the worldwide tour, 'The Return of the Spice Girls,' she put forward the idea of me creating all their costumes to which I immediately agreed. At their debut, the Spice Girls generated a trend with their individual looks and now, 10 years later, they have put their trust in me."

Among the outfits are their individually personalized uniforms (Baby, Sporty and Scary are back!), plus white and black tuxedos, silver space-age uniforms, shiny minidresses embroidered with Swarovski crystals and feathers, sensual leather corsets, and brightly colored jumpsuits.

The tour kicks off Dec. 2 in Vancouver. They can also be seen performing on the Victoria's Secret Fashion Show Dec. 4 on CBS.
