My mother in-law is throwing a reception in MI two weeks after our Los Angeles wedding. She has made two demands regarding the wedding and I do not agree with either. The first I strongly opposed to, which caused a big fight. We are having a Jewish ceremony and she wanted a Christian Minister to bless us. The second demand she is making, and at this point threatening to cancel the reception if I do not oblige, is for me to re-rent my wedding dress and wear it in MI. I decided to rent my dress to keep the cost down. I proposed to her I could wear a white party dress, since no one else will be in white, but she wants THE dress. Should I just do it for her even though it is not what I would be comfortable in?
