FI and I have been thinking about who we would like to include in our wedding party and have come up with 8 per side. We haven't asked anyone yet besides the MOH (this isn't going to change as it's my sister) but I keep feeling that having such a large wedding party is going to look funny at a casual wedding (meaning we are totally fine with our guests showing up in jeans and a t-shirt if this is what makes them happy). Would you side eye a large wedding party for a non-formal wedding?
For the remainder of the BM's, I plan to ask my best friend from college, FI's sister, and a group of 5 ladies that are my nearest and dearest where we live. FI says that we should have who we want and not worry about what others think but I'm unsure about etiquette in this.
