Of Tights and Fashion

May I know if any of you ladies wear tights as trousers by itself?

Do not mean to be rude but am so very put off by the sight of female bums in tights. Is it not obscene to be able to see the derriere's outline so clearly. It is like underwear.

And so many young gals are actually wearing it by itself these days. Is that still a fashion trend? And we are not exactly in autumn/winter or going horseriding.
