I am wearing a Vera Wang ivory sheath dress with a black sash. The ceremony is taking place in a botanical garden and the reception at my fiance's parent's house by the ocean. The bridesmaids are wearing different color pastel cocktail dresses with floral motifs. What should the groomsmen wear? Or, the groom for that matter? I was thinking of khaki pants and navy blazers for the groomsmen with different color pastel ties... But what would my groom wear in this scenario? Would navy clash with my black sash?
