Thoughts:
For Philanthropy round, my chapter always wears purple tops (deep purple, not lavender, not magenta!) with a nice bottom- most of the girls wore pencil skirts, though I believe there were a handful of pants.
Or, you could go the route we went for the first round this year- white Oxfords (bought by each member so that it fit HER) that were taken to get our crest and Alpha Chi Omega embroidered over the heart. They turned out super cute! We wore them with jeans and black or white or nude tank tops, but yo could wear them with some dress pants to dress things up too.
