I have to ask neutral parties--is it unreasonable to ask a sibling to not bring a date to your bridal shower? My sister has a new girlfriend, whom I have met twice, but I don't really know her yet. The girlfriend was not invited to my bridal shower. My sister asked if she can bring her. The hostess (our other sister) asked my opinion, and I said no. I don't know her, and I wouldn't invite anyone I don't know to a shower. Should we make an exception because we are immediate family?
