For those of you actually having your ceremony outdoors....what kind of shoes are you wearing?? I found some shoes that I love but I'm afraid that the heel will get stuck in the ground if it is even a little bit damp out.....do you think it is neccesary to go with shoes that have something other than the typical pump style heels??? This is really the only kind I every wear and am afraid to try something else! What do you think??
