I was hoping someone here could help me out on this one. I told my FI that I would like to have my brother as one of his groomsmen (My brother is of the traditional type and would be much happier standing on Greg's side than mine). My FI mentioned that his sister (one of my BM's) had asked him about her husband being a groomsmen, and he feels like he is being told who can be in his bridal party.
What is the etiquette, or "rule" here? Should he ask his sister's husband to be a GM because she's a BM, or because he's his brother-in-law? He's not super-close with him, but is probably closer to him than he is to my brother.
Any input here would be fabulous. Thanks!!
