I have a friend at work, who has a 16 year old daughter, who wore something very similar to that to school just last week!!!!
I see that you are in Reading, and I'm in State College, so the weather must be similar!!!
Crazy girls!!!!
On the other hand, my sister, who is also 16, is smart. She wears whatever is comfortable to school. I didn't do that when I was in high school either, had to "dress up" all the time

I learned when I went to college that comfort (and warmth) was what counted!!!!

I do see a lot of these younger sorority girl types walking around Penn State's campus in skirts in the winter too---amazing!!!!!
