My future husband is set on wearing a suit at our wedding. My mother and friends are telling me that since our wedding is formal, it is important that he wear a tux, as a tux is more dressy than a suit. I personally have no idea what the difference is (not on the up and up with male fashion). I certainly do not want anyone to outshine my man on his big day in terms of attire, so if we are having a formal evening wedding, should he be in a suit or a tux? Thanks knotties!
