Should I ask my fiance's sisters to be bridesmaids? He has two sisters one sister I met once and she only said Hi to me the whole weekend.. the other sister and I have met a few times and we get along pretty well. My fiance says that I shouldn't ask them because then we will have to many people in our wedding party since we both already have 5 each, but I feel like I'm supposed to ask them to be in it what should I do?
