I believe that leggings are not, and never should, be worn as pants. I like to pretend like I know what's going on in the fashion world, just like a million other 20 something girls.
The other day, while investigating the case of denim on denim, I found this pic.
This is how denim on denim can go horribly wrong. What the hell happened to her pants? Its like the weather was around 68 degrees, and she couldn't figure out if it was shorts or pants weather. So she decided to go with both. Fashion Fail.
