At the chapter I advised, we alumnae knew better than to appear on the recruitment floor without being dressed nicely. Usually, the recruitment chair would try to tell us the theme days ahead of time. That way, for example, if the girls were going to wear teal and black one round, the alums would attempt to wear some kind of age-appropriate teal or black ensemble just to help coordinate the look. Casual clothes, such as jeans and t-shirts, were OK only if working behind the scenes in tabulations or something like that.
