My fiance and I are having a very small private ceremony (15 people) in Niagara Falls,NY (we live in Mich but are going to NY because it's legal there for us) and then having a big reception the week after. My best friend's parents will be invited to the reception portion (they are great!) but since we are limiting the ceremony to closest family and best friends her parents aren't invited to the ceremony. Anyway my best friends mom wants to throw us our wedding shower (which she volunteered to do and is really excited about it) but now I feel obligated to invite them to the ceremony. Would it be ok to still not have them at the ceremony or is that rude? thanks!!
