I would prefer black shoes. I do not have a height requirement of any kind. If one is worried about being in heels all day, please wear flats. If one is vertically challenged and feels the need for a lift, hit the heels. My only great concern is the amount of toe showing. I'd prefer a closed toe shoe, however, I would never say no to a peep toe. My reasoning is this: I do not want to have to dictate what color toe nail polish everyone must wear, that's just silly. As this is also a semi formal event, I really don't want to see more foot than shoe. Finally, let's face it, none of us are extremely tan. A stark white foot underneath a beautiful, black bridesmaid dress will be rather distracting.
I think that exhausts all kinds of shoe/foot logic. I think my mom and I will have fabric sent out by October... I think. I know that I'm anxious for everything to get rolling.
