See-through yoga pants a problem for maker Lululemon NEW YORK, March 19 (UPI) -- As the stock price of clothing manufacturer Lululemon Athletica drops, the company says it may recall its accidentally produced see-through yoga pants. Lululemon stores reported a sales increase of 11 percent in the current quarter, but its stock price dropped 4 percent on news its iconic black yoga pants have "a bleeding dye issue," The Wall Street Journal reported Tuesday. The result is pants that are "sheer, very sheer, as in see-through," the newspaper said, noting nearly 20 percent of the new clothes may have to be recalled, taking a big bite out of revenue projections. The wealth management firm D. A. Davidson and Co. pointed out the see-through pants issue exposes problems with the company's supply chain, as well as the exposure customers get when they wear the pants, reporting "the combination of rapid growth [of Lululemon] and very high quality standards can cause strain on the supply chain."
