Absolutely not! The purpose of a wedding is to vow and commit yourself to your partner in a meaningful and memorable way, and you can choose to do so however you decide is best.
I’ve know brides that just have too many friends and don’t want the disappointment and hurt feelings that go along with choosing just a few girls as their bridesmaids. One remedy for this is to either not have any bridesmaids at all, or maybe just have a sibling stand by you as your best girl at the altar.
Remember, this is your special day, so if you’d like to throw all traditions out the window and get creative with your own vision of what you’d like your perfect wedding to be like, go for it!
