Apparently, women’s underwear that pops out and is visible to others is a problem in yoga classes. (Who knew?) Now, a North Carolina company called YoginiStyle is coming to the rescue with its “revolutionary” YogaSmart pants. The company is marketing the pantaloons thusly: “These low-rise fitted pants have panties attached in five different locations around the waistband to keep panties from playing “peek-a-boo” while in your favorite yoga positions.” At 60 bucks a pop, it strikes us as a rather costly solution. Here’s a cheaper one: don’t wear low-rise pants when doing yoga. No charge.
