vintage inspired wears for maid of honor in tea length

We have been tasked with drinks for Saturday. There will be plenty of water at each field. I'll be bringing two five-gallon jugs of either iced tea or lemonade. So if you bring like a two or three liter of soda/tea/whatever per family vintage inspired wears for maid of honor in tea length :) we should be okay. Jen Tyler, you can substitute soda for no-bakes.
