The tour kicked off on Sunday in Vancouver and will include more than 30 dates across Europe and the United States.

Cavalli said he was asked to design the British pop group's tour wardrobe by fashion icon, Victoria Beckham, also known as Posh Spice, whom he has known for many years.

"She put forward the idea of me creating all their costumes to which I immediately agreed," Cavalli said in a statement.

"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 to get a new, unique and iconic appeal for the tour," he said.

"The Spice Girls are one of the biggest global success stories with their appeal crossing many generations and millions of fans awaiting their return. When I met them, I immediately understood the reason why the world went crazy for their unique brand of 'girl power,' as they are an irresistible mix of energy, pure joy, humor and a spicy dash of glamor."
