Business for Steve Madden Ltd. is booming, according to the company’s first-quarter report, which showed a net income increase of 16 percent compared to this time last year; fiscal 2011 revenue is predicted to rise between 20 percent and 22 percent. Why? Their shoes are right on trend, apparently: “The trend-right merchandise assortment created by Steve and his design team enabled us to deliver solid top- and bottom-line gains,” said CEO Edward Rosenfeld. Said trends are defined by four categories on the Steve Madden website: “nude attitude,” “bows,” “espadrilles,” and our personal favorite, “glitter.” And just think, this will only get better (or worse?) if Katy Perry gets on board.
