That may be a southern school/sorority thing. My oldest went to UNC and was in a sorority and they wore dresses to football games. Her friends at UGA & UofSC also wore dresses for football games (also sorority girls). Like you said, there are plenty that don’t dress up. D21 is relieved that her college (VT) has a laid-back, casual vibe. She packed dresses in anticipation of having to wear them to football games, but never did. They do wear the ripped jeans and cropped tops, which aren’t my fave but I think that’s a generational thing.
