I am having a hard time deciding the groom and groomsmen attire. My bridesmaids are wearing dark navy long chiffon dresses. My fiance wants to wear his black tux and have the groomsmen in a gray (slightly on the darker scale, not charcoal) tux. They would all wear black shoes and black ties and no vest to try to make their outfits a little less formal. Do you think that will clash? I've been looking around and I think I like it, but just can't decide. Someone then said that the groomsmen could wear navy ties and brown shoes, and have the groom in all black, but I think it would look better if they coordinated. What do you think? Any advise is appreciated.
