The Best Man, my fiance's brother, will have just graduated from basic training when we are having our wedding. We are already planning out date around when he can attend, and he is insisting that he wear his dress uniform for the ceremony. The groom and the rest of the groomsmen will be wearing black suits with purple ties. Is it ok that I insist he wear a suit like everyone else? And if so what is a good way to do so and still let him know I am proud of his service in the army.
