Girl these days go out in public wearing see through tights as pants. My reactions when I see this is what kind of friends do you have that will let you walk out in those.
Leggings or Jeggings ( Jean-leggings) are fine to wear as pants. But wearing tight that people can see you undergarment is not a fashionable idea , it’s a fashion faux pas.
Girls should not let other Girls make a fashion faux pas.
