On Sunday evening, on the way to the Emporio Armani fashion show here, I did what I always do with … oh, six free minutes of my day: I checked eBay.

Perhaps to get in the Armani spirit, I searched “vintage Armani” (a search I’ve had saved in my account for a couple of years now) and prowled through the hundreds of Armani jackets, shirts and knits that have washed up on the site.

Half an hour later, watching the Emporio show, I began to feel as if my eBay search had sprung to life.

There, in front of me, were sandy-hued chevron sweaters, ripply cigar-brown leather blazers, waist-length insulated jackets with paperback-scaled pockets tacked on the front and suits buttoned, for maximum drama, at the collar: all cousins, if not brothers, of items I’d seen on eBay.

The 120-look buffet (Armani does not skimp on its model budget) was a reminder that Giorgio Armani, the Italian titan who, at 90, continues to look hale in his unwavering navy T-shirts, long ago found his design language — and he’s sticking to it. To start speaking a new dialect now would be illogical and, for Armani’s legion of consumers, destabilizing.
