we are getting married on the beach at sunset. Dress is upscale casual. My bridesmaids are wearing strapless babyblue dresses, my fiance is wearing an off white,kaki linen suit and i am wearing a strapless ivory dress. What do the groomsmen where? HELP....wedding is in 5 weeks! If they wear light blue shirts,might be too much blue.....if they wore white and blue shirts, would it clash with my ivory dress???
