Input: My fiancé is friends with my younger sister, but doesn’t know my older sister well at all. 

We’re getting married in two weeks, and my fiancé asked my younger sister to be a bridesmaid at our wedding. My older sister heard about this and apparently (she told my family) is upset about it. 

It doesn’t seem reasonable to me that my fiancé should be expected ask someone she barely knows to be a bridesmaid. 

On the other hand though, she’s going to be the only sibling (besides another brother who can’t make it to the wedding) who is not part of the wedding party. My older brother is my best man.

AITA?

TL;DR family is upset that I didn’t ask my fiancé to make my sister a bridesmaid (she asked my other sister, who she is somewhat close with)

not asking my fiancé to make my older sister a bridesmaid
