I don't have a problem with most people wearing them, so long as it's not an utterly slutty way of dressing.
Which tends to consist of wearing the tightest leggings posible, normally some horrible leopard print, not wearing anything that really covers the bum, and then practically shoving it at people.
And some girls at my College do that, and it's disgusting and vulgar.
There are normal ways to wear them and not do this. Some of my friends wear leggings and it looks absolutely normal. You wouldn't even second-guess it.
All they need to do is put on some shorts or skirt on over-top, or have a long cardigan/jumper on.
The problem with leggings is that they are obscene in the pelvic region. Having skin-tight clothing stretched across your groin and bum is not something you want to see in a public place.
They're called leggings. The most important part about them is how they make your legs look. Not your groin and arse.
And as horrible as it is to say, fat ugly people should not be allowed to wear them.
I don't care if it makes them feel pretty. It's is absolutely revolting and exceedingly unattractive.
And in my personal experience, they tend to be the ones trying to make it look slutty.
Putting a fat girl in skin-tight leggings is just trying to make them the biggest uggo munters going.
