Reasons to wait until the ceremony to see your betrothed are obvious... the romance, the suspense, the anticipation! But logistically it might be better to have an intimate moment with your future spouse before the wedding, due to time constraints, or to give you and your wedding party more opportunities for pictures. And to just have a moment to yourselves before all the craziness starts.
What do you think? Would you (or did you) wait until the wedding ceremony to see your spouse-to-be? Or are you in favor of a "first look" session?
