I'm not sure. What is your groom wearing? We went to a friend's wedding in October, and the groom wore white. I've always imagined him wearing a darker color but I do think that looks kind of classy. I'm sure he would look handsome in anything!
...as long as he's gonna take it off after this thing is over! 
Does anybody know if this is more of a "current trend"?
...does it really matter?
