Tapestry, the company previously called Coach, reported a loss of $18 million on sales of $1.29 billion for its first quarter, ended Sept. 30. The sales increase of 24 percent and the loss were partly due to the acquisition in July of Kate Spade and costs for its subsequent integration. The group reported a 10 percent increase to $96 million in Stuart Weitzman's sales for the quarter, which generated a slightly reduced gross margin of 49.4 percent of sales and a much improved operating margin of 8.7 percent. Revenues from the Coach brand were down by 3 percent.
