My fiancé has 5 sisters, ranging from 25 to 5. Tonight, his 12 year old sister told me that she wants to be a bridesmaid. I would feel bad having one, but not all five of them. I want a small wedding party. Also, his mom would have to pay for 3 dresses if I had all of the girls in the wedding. They don't have the money to buy three dresses. How should I handle this? I don't want to cause drama while I have all of the other details of the wedding to work out.
