I am starting to plan my wedding, without making my anxiety any higher than it is. I am planning a small wedding with less than 50 people. The ceremony will not be in a church. Friends suggested I have to at least have my two sisters as bridesmaids. I have only been to a few weddings and never been a bridesmaid so I am not sure what they would actually contribute. I had thought that I would not have any bridesmaids. Is it that unusual?
