I haven't got any specific dresses in mind yet, but i just wondered if in principle this was a very bad idea. I've always been a hippy at heart and i'm starting to learn to reflect that in my clothes, rather than the head to toe Next i'd got used to wearing... but i don't know if it's a bit much for a wedding? don't want to ruin the photos! was thinking of hippyish flat sandals to go with, but not sure.
