This theory is in the lab. One of the reasons is b/c there are some super hot chicks that wear over-sized sunglasses and this is where my sub-theory enters: insecurity. Either a girl has something to hide or she has found the ultimate accessory to mask her insecurity. Even 4's (standard 1-4 grading scale) get insecure.

Maybe sometimes, but most of the time these days imo they are just trying to follow the trend they see outside and in celebrity magazines. That behavior definitely can say something about a girl, but it's not necessarily insecurity.
