What to do with my hair for my wedding?

With hair that long, you should have hired a stylist. They would have had at least one trial appointment with you to figure out what to do with your hair, but at that length it would probably cost hundreds more than another bride with shorter hair. If your wedding is tomorrow there's no time for a haircut because all the decent salons will be booked up. You can't walk into a Fantastic Sams on your wedding day and get a cut, you'll end up looking like squirrels nibbled your hair off. Just pull your hair back into a ponytail or bun.
