As other people have said carrying modest white and black dresses year round would work very well because these things can be impossible to find. But I also think it would work well to reach out to not just to sorority girls by selling things like dresses that are in alabama's colors to wear on game day and also selling jewerly and the alike. Once the school year sets in you could also carry dresses for formals.
I have also noticed on bid day pictures from schools in the south, that sorority members tend to wear dresses that are their sorority's colors on bid day. So you could look up those colors and buy dresses in the sororities colors. This would also cater to the non greek girls because they would see them as just cute dresses to wear for differnt events such as church and weddings.
