What’s that saying? You have to know where you came from to know where you’re going? As Norma Kamali prepares to move out of her longtime uptown space and build on her women’s empowerment project, Stop Objectification, with a new Web site and forthcoming documentary, it made sense that she rediscovered some old favorites for spring. “This collection is my fresh take on what I did back in the day,” said the designer, pointing out a body-con dress covered in white studs and noting that the original had been done in silver. There were also sexy jersey halter dresses with high collars, à la Studio 54, and matching denim jackets and jeans — a uniform for many in the Eighties — updated in a snake print. Kamali has always had a way with found objects (remember her sleeping bag coat and parachute dresses?), and this time, she fashioned handmade fishing nets from Brazil into a series of pretty dresses that felt right on trend.
