Stepping into Gregory Parkinson's Resort presentation on Friday instantly alleviated the New York gloom. Parkinson is based in L.A.—he has that effect on a girl. But his new collection of artfully mismatched tops and skirts was especially bright. Their mood-enhancing properties seemed to have rubbed off, even on him: "I'd like to do these kinds of clothes twelve months a year," he said. The idea couldn't have been simpler: Parkinson sewed jersey tanks or tees inside out, so the faded, slightly blurred reverse sides of the prints were showing, then paired them with below-the-knee, full skirts in clashing prints. He's got a fun, fearless way with color and pattern, and it was back in full evidence after a mostly black Fall collection. A couple of other positive developments: His newly launched e-commerce site is now accepting orders, and, even better, he's working on a home-furnishings collection.
