We could tell you how Michael Kors arrived at tomboy glamour. It has something to do with his distaste for the term Pre-Fall, the increasing irrelevance of seasons in general, and the realization that a boy's wardrobe is seasonless—just the thing for clothes that arrive in stores in May and linger through November. But what does it matter when the clothes in question look this good?

He opened with a double-breasted camel coat, an oversize blue shirt, and slouchy yet tailored gray pants, worn with crocodile sneakers, a first for the label. Menswear vibe established, he started riffing: embroidering sky-blue chinos with rhinestones in a paisley motif, accessorizing a foulard-print pantsuit with matching loafers and zip pouches, morphing a rep scarf into a pleated skirt, and cutting a black-and-white houndstooth fabric into a strapless dress. The look that best captured the collection's feminine swagger was a cashgora robe coat in fawn (a light brown), tossed over a black cashmere sweater and full-leg scarlet trousers. The flat shoes were key. He even believes in them for evening. A gorgeous black sequined dress over-embroidered in crystals was shown with shiny black oxfords.

Kors has a new name for Pre-Fall. He's calling it "trans." We're not sure that's a moniker that will stick, but there's no doubting that these clothes will.
