I'm not really sure of what's expected as far as siblings of you fiance in the wedding party, and would like some traditional advice. I know that nowadays everyone says "just include your closest friends"...but is there actually an assumption from parents, etc, that the siblings should be included?
Situation: For background, I'm 23 and fiance is 26.
I have three younger siblings, two brothers and a sister and I'm extremely close to all of them. My sister (age 17) is co-maid of honor (along with my childhood bff). My littlest brother (age 12) is the ringbearer. I would like my brother (age 21) to be included as well, preferably as a groomsman. Fiance likes my brother and they actually knew each other before Fiance and I met, but I know they're not best friends or anything.
Fiance has two older sisters, age 29 and 32. He is on good terms with them, and family is very important to him, but they're not extremely close personally. I've known them for the 2ish years we've been together, but don't see them super often, and just because of age differences and personalities we haven't gotten close - I like them but they're not the kind of girls that I think I would be good friends with.
I already have 5 BM's that I would like, and fiance has 5 GM as well. He says now that he would include my brother, but only if I also include his sisters, which is fair I guess. We kind of didn't want a huge party though.
Questions: How expected is it to have siblings in the wedding party? Will his sisters be offended if I don't choose them?
Should I go ahead and choose them so that my brother can be part of it? We'll each have 6 or 7 then.
Or, should I have my brother be on my side and his sisters can be on his side? I know people say that male/female doesn't matter, but I personally haven't seen that before in real life. How does that work? What do they wear, do they go to bachelor/ette party or not, etc?
Also....fiance is very traditional, as is my brother. I honestly doubt either of them will go for the opposite sex wedding party thing.
Thanks everyone!
