Does anyone know if the groom''s/ groomsmen''s tuxes are supposed to be buttoned or unbuttoned during the ceremony? My fiance and I like the unbuttoned look (at least for the reception) but is it too informal for the actual ceremony? (We''re having a very traditional ceremony in a church...) I tried to google it and didn''t find an answer so I was wondering if anyone here knew... What are you all doing for your ceremonies?
