We wanted to keep ALL family out of the wedding party, but my arm is being twisted to let the FH'S sister be a bridesmaid. Family guilt trips might win out, but I'd prefer to keep the sister out of it.
Sister-in-law is our officiant instead or one of my bridesmaids. She is a Sunday School teacher, cheer coach, and a public school teacher so we trust her oratory skills, and one of the first champions of our relationship so it was the perfect fit!
My FH has one sister and we are really close. She is a bridesmaid in our wedding. She is also marrying my FH best friend next year and he is the Best Man in our wedding. We will be part of their bridal party next year when they get married too!
Also my brothers wife has become one of my best friends and she is my Matron of Honor.
DH has 5 sisters, the youngest when we married was 22, every one of them already married with kids, kind of been-there -done -that. as bridesmaids for friends and their 22 female first cousins who live near them! Which pleased me no end , because though we get along on the surface, we have nothing in common. And first thing on hearing of our engagement, one of his aunts and a grandmother both sat there making the decision ( they thought ) of which ones would be in our wedding party. Alarming, as I did not want any of them, and was not asking my 4 sisters either. A great escape for me, that they were each sick of wedding stuff.
Every wedding I've ever been a BM in has had the in laws in the bridal party. We're Jewish and there is a word "machatunim" which basically means your spouses family becomes your family. I'm honestly shocked when I don't see people include their sister in-law/brother in-law in their bridal party.
Fortunately, no. I'd hate to be blunt, but no one likes my FH's brother's wife - not even my FH's parents. She's rude, she thinks she's always right, she has weird beliefs. More or less, she's a lazy, entitled you-know-what. Thankfully, she lives out-of-state, so we never have to see her!
FH's sister is a bridesmaid of mine. FH lost his dad when he was 19 and his mom has severe dementia so his siblings are very important in his life. After 7.5 years together, his sister is family to me already so I wouldn't have it any other way. His brothers are groomsmen for him. Family is everything
I think it honestly depends on what you are comfortable with and who you two are close to. When we discussed our party, my FH had BP problem including my brother as a groomsman, because they get along well. He's become the younger brother he didnt have, especially because my brother is quiet and reserved and it's an enjoyable trait when you work with craziness every day. But on the flip side, my FH has a twin brother that he will include as a groomsman, mostly because of tradition and the right thing to do. But he has no qualms of kicking his brother out iif they aren't getting along and pick another close friend who will be invited. My FH and his twin will get along one day and then his twin will start a fight and they won't talk for 6 months. So really it's what you two are happy with, regardless of tradition!
