Regulars at yoga classes often praise the liberating nature of the ancient Indian exercise  but sometimes things can get a little bit too liberating: enter yoga clothing maker Lululemon LULU -3.77%, which has withdrawn shipments of its women’s yoga pants that fall short on the “coverage” front.

Apparently due to a problem at the factory, there is “a level of sheerness in some of our women’s black Luon bottoms that falls short of our very high standards,” the company said today.

Excessively see-through yoga pants! We have a situation on our hands here. Lululemon says the problem affects about 17% of all the ladies pants in its stores, and that’s a problem for a yoga pants company in a land where nude yoga has yet to take off: Lululemon stock fell 3.8% today and is down another 5.2% in after-hours trading.
