Sheree Watson will leave the Vancouver-based company on April 15.
Last month, Lululemon began pulling its popular black yoga pants because they were too sheer. In a statement on its website at the time, Lululemon said, "The materials used in construction were the same, but the coverage was not, resulting in increased sheerness."
Lululemon says the problem stemmed from incomplete testing protocols, combined with a style change in the pants pattern.
