Sorors,
definitely bring the (unadorned) white dress/skirt suit. you will not get into the plenary when the Honoraries are installed if you're dressed incorrectly. pink, green, and neutrals are a good idea, plus make sure you have cool clothes (it's supposed to be hot), check The Weather Channel prior to leaving. do remember your very comfortable shoes . you will be walking a lot.
my tips, as a Boule vet...4 and counting...
