I personally prefer men in lighter suits on wedding day. Classic black is too unhappy and besides what could ever be more boring (sorry white tie and black tie options) than classic black suit. Wedding day should be of fashion fun for both men and women. Why don't us pick unusual dress shirt colour and some cool details with contrast on shirt and tie? Why don't you make a theme colour and complement it with additional colour on your suit or a wedding dress?
black shirt and metallic tie? for me it's a little to much for husband-to-be but can very cool for guest or a best man.
