My family expects me to wear traditional clothes at my cousin's wedding. I do not feel comfortable in them.

I usually wear simple jeans and tops. For the wedding, my aunts keep saying, "Wear a saree, at least for the main ceremony." I do not feel like myself in it, and I worry about tripping and feeling stiff all day. I offered a compromise: a modern salwar suit. They said it is too plain. My mother asked me to do it "just this once" for the family. I do not want to start a quarrel, but I also dislike being told what to wear.
