If a family member throws you a bridal shower and the shower is ONLY for family members, then it really doesn't matter that you're technically breaking the etiquette rule, right? My sister is going to throw me a shower the day before my wedding b/c ALL of my family members live out of state and will only be there the weekend of the wedding. We've told the ladies in our family (which isn't a large group) and they are perfectly ok with it.
