I'm interested in joining a sorority, and they're having their first informational night tomorrow. The invitation says business attire is required. I don't own business attire! I have dress pants, and nice shoes, but when it comes to tops, well, I'm lacking in that department. I have a couple of nicer cardigans that I could possibly wear over another shirt, and I also have a couple of nicer shirts that are like flowy blouses. Help!
