My FI has decided that he wants three groomsmen while there will be only two bridesmaids. I really have no problem with this, but one of his groomsmen is in the Air Force and generally wears his dress uniform for formal events. I'm just worried that since the numbers will already be off, if he wears something completely different than the other two guys, it will look like we just stuck him in there. Is it rude to ask him to wear the same as the other guys or should I just let him wear his uniform? Also, if he wears his uniform, does he still wear a boutonniere? Just thinking I'm not sure where it would go with all his badges and stuff on his jacket. Any fashion advice or anyone with military experience would be appreciated. Thanks!
