As Christa said, I plan on doing the ceremony barefoot, and then flipflops or a very small heel for afterwards. I do have a smallish train on my dress and would really like to wear it down as well, since the detail on it was half the reason I bought the dress! It's pretty light, and I know some sand will get on it, but hopefully it won't cause me any issues. I do have nightmares about it getting stuck on the runner thing I will be walking on and snagging, or pulling me down, but I assume that's just me being a worrysome bride!
Any married gals with advice or calming words?
