my older brothers wife had a long dress that cvered her yellow ballerina slippers. you could see them at the reception. not during the wedding, which i think would have been ugly looking. if your dress is long and somewhat covers them i, i dont see why your mom would disapprove THAT much. i agree, it doesn't sound all that great, but its your darn wedding, you do what you want to do. gracefully accept (unwanted) advice and critizism, but dont make any promises. you dont have to answer to anyone or make any excuses on your special day. congrats and best wishes
