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.
Heads Up: Grey Jeans
In addition to the ever popular colored skinny jeans, grey jeans will be taking a lead role this fall. Grey jeans are one of my faves. They literally go with everything. They can take the place of your blue skinny jeans, because they are just a neutral. I like them because they are a nice way to mix it up if your fall uniform is skinny blue jeans, an oversized sweater, and flats. That would be my uniform.
