I asked my two sisters to be bridesmaids back in October. My fiance and I asked them when we were all together because we thought it would be special and one sister was so excited while the other did not say yes right away and instead flat out asked "do I have to wear a dress?" I told her I wanted everyone to be in the same color dress but different styles that best suit them. She then proceeded to throw a temper tantrum in front of everyone and I was absolutely crushed about her reaction. My fiance is livid but is understanding she is my sister and that I want her by my side for our big day. My mother says my sister wants to be there to support me but wearing a dress makes her uncomfortable and is torn between making me happy and my sister happy. At the same time, my mother understands this day is not about my sister and ultimately it is my fiance's and my decision going forward.
I have gone on websites to look at rompers that look like gowns to see if I can meet her halfway and compromise. I am understanding of the fact that she doesn't like dresses and even am going to throw in the option of her wearing the dress for just the ceremony and the part of the reception where we introduce the bride and groom and their party. But in the end of my researching, my heart is set on all of my bridesmaids wearing dresses. It would make me happy to have her in my party and be able to celebrate this exciting time along with us. But, she's making me feel miserable and was incredibly rude to me and my fiance when we asked that it concerns me she will act out at our wedding as a result of me asking her to wear a dress. I've looked on so many community forums and reached dead ends that I decided to post something because I honestly have no idea what to do.
Anyone have any suggestions in how I should handle this situation? I honestly don't want to end up having to say to her she cannot be a bridesmaid because she won't wear a dress because it would break my heart to not have her involved. At the same time, I don't want her to be uncomfortable to the point where she will act out or resent me.
