I am not 100% certain these are Wunder Under. This pair of Lululemon Leggings has no size dot that I can find. Please use measurements in photo to use as a guide. These are the tight leggings with a super high or roll down waist. Needs a good lint roll. Otherwise in excellent shape. Crisp black color I am pricing these at a bargain because of lack of concrete information. Base your purchase on representation in photos and measurements. U517
