A MAN FOR ALL SEASONS: Azzedine Alaïa confirmed Monday he will join Paris couture week and do a “small showing” of ready-to-wear on Jan. 23 at his Paris headquarters. But trust fashion’s most resolute individualist to do it his way. While Yohji Yamamoto will show fall 2003 ready-to-wear and couturiers will show summer designs, Alaïa promises looks for all four seasons. “It’ll be a real mix,” he said. Also expect a glimpse of his new eyewear, made in collaboration with Alain Mikli, and an expanded collection of handbags.
