“Go with what you know” seems to be Gaia Trussardi’s game plan for making an apparel business out of her house’s leather heritage. The overwhelming majority of her spring collection was leather — perforated suede, ostrich, napa and elaphe leather — dyed in the bourgeois tones of burgundy and navy and good old-fashioned tan, with some green and cobalt to brighten.

The shapes, too, followed the tried and true with a slight athletic slant.

Trussardi’s show notes mentioned her quest for “an Olympian ideal.” Car coats, moto jackets, tennis dresses and skirts, bombers and utility shirts were all done in some sort of classic skin — Trussardi didn’t go the route of technical tricks. Maybe she should have. Looks such as a cable-knit or a little polo top emphasized that this was a wardrobe of country club clothes, costly and cautious.
