Tamara Mellon's ambition is no less than to change the entire fashion system. "It can't be a six-month gap" between when a collection is shown and when it is sold, she insists. A continuous "Endless Collection" of permanently available basics makes up the backbone of her namesake line—fine-gauge cashmere tees and tanks, upscale sweats, and the all-in-one legging boot, which doesn't look like much on the hanger but is a best seller—while the trend-driven portion is shown quarterly and delivered monthly.

"In my previous life, when we'd do things by collections, there were always too many ideas," Mellon says. Inevitably some would get cut for the cohesion of the whole. Not here. Bringing a fashion collection into the same frantic roundelay that the rest of world cycles through frees Mellon to indulge in as many mini-trends as she likes: cutout tops and dresses, inspired by a vintage photo of Veruschka, for March, fringed flapper skirts for April. There were forays into Harley-Davidson homages—in the half-length, studded-leather leggings and studded pencil skirts—though there was a hearty helping of Versace in those, too. Overall, the collection had a voracious sex appeal, which should make it salable indeed—and only more so when Mellon's e-commerce launches in mid-January, and brick-and-mortar stores, which are in the works, open in New York and London after that.

Mellon being the brains behind Jimmy Choo (read all about it in her recent memoir), attention was always paid to the shoes. And there were fine options here, from pumps to gladiator sandals, and even a few unlikely thong-cutout booties. They bear evocative names such as Wild, Tease, Basic Instinct, and, our favorite, Iconic Bitch. It goes to show that, change the system however much you like, some things will always stay the same. You still have to dress for the job you want.
