I think the most helpful source i've seen for this kinds of thing is the video someone posted from Southern Mississippi. In that video, they give two examples per dayof what the girls should wear. But that video also shows a model in jeans. And I know there are a lot of SEC shoolds that aren't to excited about jeans. But thats something you or your sister should determine by UF.
It is great that people are providing links for other schools, but I think it is important for each school to provide information specific to their culture, policies, procedures and standards. What is acceptable at one campus may not be at another. Furthermore at least one poster has stated this is old information.
