Lululemon pulls yoga pants _ too revealing

The company insisted it had not changed the specifications for the clothing, but is warning of a shortage of the extraordinarily popular clothing items, which make up make up about 17 percent of all women's pants and crop pants in its stores.

Shares dropped more than 5 percent in morning trading Tuesday and one analyst that follows the company stripped it of its "Buy" rating.

Sam Poser of Sterne, Agee & Leach advised clients to take a wait-and-see approach until the problem is resolved. He downgraded the company's shares to "Neutral."

There appears to be a "major quality control problem" in Asia where the "Luon" pants are made, Poser said. While Lululemon has used the same factories to make its fabrics since 2004, he said it doesn't seem as though the company has the proper oversight in place.

The Luon pants are one of the retailer's product staples and Cowen analyst Faye Landes said that if there is any comfort to be found, it is that Lululemon is not facing a demand problem. Lululemon has been a star for investors, as well as yoga devotees, with shares rocketing from less than $3 in 2009, to around $65 this year.
