I am not sure what I would need these for, at least the leggings were proposed as a comfortable substitute for pants or sweatpants. Perhaps the pantyhose or "feel-good knee-high hosiery" are "made to help drain toxins and massage tired limbs".
The new fashion "trends" make it easier and easier for me to ignore them because they stretch the bounds of credibility to irrelevance. I'll be saying this right up to the point that I am wearing these things just because everybody else is doing it.
