I workout with leggings and wonder which option reduces whale tailing.

A string’s waistband is much thinner than a thong’s. Does this mean whale tailing happens more often with strings than with thongs? If the waistband is not a string, but a wider piece of fabric, the piece should stay where it should be longer than a string and the waistband won’t ride over my hips when I workout, jump or stretch.

Is this how it works?

I’m skinny and don’t have wide hips or waist, if that makes a difference.
