LOS ANGELES, CA  [Monday Nov.27.2006]  /Mix103FM.com/ -- Christina Aguilera's tour has now become a fashion-forward event.

The pop diva has hired top designer Roberto Cavalli to create the costumes for her "Back To Basics" tour, which is to kick off in the U.S. this February.

The outfits span over three decades: the forties, fifties, and sixties, and, according to Women's Wear Daily, include items like a white satin tuxedo, a silk bustier and tafetta skirt, and a fully-embroidered suit.
