I went to a northern university that did spring recruitment, so I'm not sure how much this will help you. 
For the first day of recruitment, all of the chapters always wore specific "ABC U Recruitment 20XX" t-shirts that were ordered and distributed by the Panhellenic Council. We paired ours with dark, well-fitted jeans. If House Tours were planned for this round (which was the case for most of the years I was an undergrad), we'd wear flats or riding boots. I believe all chapters wore block letter t-shirts and jeans for Philanthropy Round as well.
Other than that, outfits varied. It was basically some combination of dressy tops with jeans or dresses/skirts with tights. For Preference, we always wore black dresses.

 We used to do red accessories for the open round. We were allowed to wear outfits in colors that pair well with red and then we'd all wear a couple of different red accessories that complemented our outfits.
