I think the white shorts and a nice blouse would be fine--watch for VPL though. Casual for set I will be fine I am sure, the days should get progressively dressier. I have always maintained that being over-dressed is better than under-dressed, but there is a fine line there--I wouldn't wear anything fancier than sun and day dresses up until set III. Personally, I hope that the days go that late. Yes, we will be tired, but the longer the day, the longer we spent at each house discerning if it could be our future home or not. Besides, I think it's a fair bet that the sorority women will be much more tired than us, they have to worry about set up and clean up, when we get to fill out our days choices and go to sleep
