My mother and I are presently having an issue about tznius. I wear long skirts and when skirts are just past the knee or a little longer, I wear pants underneath. I also prefer to wear long sleeves rather than 3/4 sleeves, and I generally do not wear red. My mother thinks that all this is unnecessary, and won't let me out of the house in more than two layers during the summer, although I never get overheated. If I feel that dressing this way is essential to my Judiasm, do I have to listen to my mother?
