A NEW MAN: There’s been a changing of the guard in Bloomingdale’s fashion office. Justin Berkowitz has joined the retailer as fashion director of men’s. He will report to Kevin Harter, vice president for fashion direction of men’s and home. He succeeds Josh Peskowitz, who recently left Bloomingdale’s to open his own men’s store in Los Angeles. That store, Magasin, a new men’s multibrand store, is expected to open on Feb. 20. Berkowitz was most recently senior market editor for Details, and previously held editorial positions at Teen Vogue and Marie Claire.
