So I've got my ideal 5 guys in my head I'd like to stand with me as I marry my fiance. Now it's time to ask them. I'm sure 4 of them will accept but one lives out of state. He says he'll be able to attend but here's my problem. Just his travel expenses to be present at our wedding will total near $600 round trip. Is it bad form to ask him to be a groomsman which is going to cost him an additional $150-180 for his tuxedo rental? We've taken a hard stance that the wedding party will be paying for their attire.
Let him pay for everything, since that is your "policy," but slip him a couple hundred as a thank you. Maybe send it to him in advance so you don't have to worry about anyone seeing you do it.
