On the heels of a more aggressive and hard-edged women’s show for fall, Roberto Cavalli cranked up the machismo factor for his men’s spring collection. There were military details like elaborate epaulets and toggles on strong-shouldered jackets, industrial hardware used as beading, and leather pants and jackets with elaborate laser cutting and embossing. Mixing some tender in with the tough, the designer sent out a parade of pastel colored, gauzy muscle shirts with armholes down to the waist and zip-fly trousers that had an extended waist that folded over. But even they seemed to say: Don’t mess with me.
