My sister is 8 years younger than I am. I think that she is too young to be a maid of honor, but still a bridesmaid. The problem is I want to have 2 matron of honors. My best friend and my sister-in-law. My sister in law and I are really close, in fact roommates. My mother is offended i would ask my sister in law over my own sister. But we are not that close. Plus i am not even including my two other sisters as bridesmaids. Am I right in this decision?
