1.) If you have to ask whether or not it's inappropriate, it probably is. "Is this too white?" Probably. "Do you think the bride will care if I wear this?" Who knows, but probably.
2.) Bring a wrap--even if the wedding is inside. Temperatures can never be predicted, even in the great indoors.
3.) Your feet will always hurt from your heels--because, dancing (unless you're Beyoncé or something). I've personally come to realize that there is no such thing as a comfortable heel, especially when you're standing/moving for hours on end. Suck it up or wear shorter heels/flats so you can cut a rug pain-free.
