PARIS — Talk about a busy week. Not only is John Galliano showing a couture collection for Christian Dior today, he’s also unveiling Galliano, his new second line produced by Italy’s IT Holding. Although priced about 40 percent less than his signature collection, the Galliano line is loaded with the designer’s touches and his range, from tough to tender. Think, for example, of a delicately ruffled, crystal-flecked chiffon top paired with camouflage pants. The designer decked out the debut spring 2007 collection with distinctive details, from newsprint linings and touches of lace to bold embroideries on the back of jean jackets blaring “Magic John.” And the line spans everything from beachwear and sweatpants — cut with a swagger — to leather jackets, suits, cocktail dresses and accessories.
