I've always had the idea when someone gets married, they include any siblings, FI siblings and close friends in the bridal party. I'm close to my FI's two sisters so I have automatically included them in the bridal party and out of proper etiquette, my FI is willing to include my two brothers on his side (although they aren't as close). Now, my older brother is getting married this year and I assumed I would ask her to be a bridesmaid when the time gets closer (we don't get married until 2016). But, as far as I know, she is not asking me to be a bridesmaid as my brother said "he had never heard of siblings being in other siblings' weddings, he wasn't even gonna consider our youngest brother..." Anyways, that's another story. But, should I still ask his future wife to be a bridesmaid in my wedding even though we aren't that close? And should I expect my FI to keep my two younger brothers on his side?
