At least one sister was in jeans that I can remember, but I wore slacks and a dressy top like the girl we had asked told us would be ok to wear. There were actually alot of pnms in jeans, even one in really really short shorts, but I am more gauging what to wear on the sisters. I just felt bad for sorority 1 because I was waay too dressy for their casual party but it turned out alot of other pnms were dressy for that party too and the seemed to be fine with it, so it all worked out in the end.
Thank you everybody though, I am really excited that tonight is through and through casual though
