Wore these under a fitted dress for a wedding and everything stayed smooth through dinner and dancing. The extra firm control really does flatten the tummy without digging in, and the high waist didn't roll down once.
I was skeptical about "extra firm" shaping, but these actually slim my waist and back without rolling down. The FitSense print really does feel like it targets the tummy area. Wore them for a 9-hour workday and barely noticed them.
