The founder of Perry Ellis International Inc., George Feldenkreis, who was ousted as executive chairman less than six months ago, is now making a bid to buy the Doral-based global clothing retailer. Feldenkreis sent a letter to the company’s board proposing a deal at $27.50 a share, or about $430 million. Feldenkreis founded Supreme International, which late became Perry Ellis, and led the company for 50 years.
