Well, on the formal nights we dressed up fancy, and on the other nights I would wear a nice pair of capri pants with a nice blouse and sandals, or even a skort and a nice blouse. Except at Lumiere's, were you are supposed to be a little dressier, and then I wore a casual sundress and was not out of place. I am not one who likes to wear dresses alot, so I was pleased to be dressed appropriately in capri pants. Oh, by the way, I took WAY to many outfits. I was in the same pickle your in. WHAT TO WEAR. It was actually alot more casual than I had imagined. Just don't be junky and you'll be fine.
