There's no one right answer for the number of guests you should invite to a bridal shower. Smaller bridal showers can be intimate, while larger bridal showers will tend to feel more festive and upbeat. The size of your bridal shower venue may help you decide what's appropriate. What's really important is knowing who to invite. Traditionally, you should invite bridesmaids, close family members from both sides of the family, and close friends. A major faux pas to avoid is inviting anyone who isn't also invited to the wedding.
