Some of my friends have been discussing this and can't seem to find an answer for it anywhere. My wedding is outdoors in front of a waterfall fountain at 3:30pm. The girls all want to wear long strapless gowns (including my own gown) but I don't know if the guys should wear a tux or just a nice suit? I've always thought that "afternoon" weddings were less formal and that a tux would look out of place. But if the girls are wearing floor-length gowns is it ok for the guys to wear a tux?
