Wilson made a fortune convincing women that nirvana was just a $100 pair of stretch pants away, but he lost his sure footing over the past two years. In March 2013, Lululemon recalled 17 percent of its black yoga pants — which don’t come in a size larger than 12 — because its proprietary Luon fabric was too sheer. Some women who tried to return the pants at Lululemon stores said they were told to put them on and bend over so staff members could determine just how see-through they were. After a monthslong public-relations disaster, Wilson, who was chairman of the company, went on Bloomberg TV that November to share what he thought was a reasonable explanation. “Some women’s bodies don’t work for the pants,” he said. “It’s really about the rubbing through the thighs, how much pressure is there over a period of time.”
