My congregation was ultra conservative. They had many insane rules they made up on their own. Sisters were "strongly encouraged" not to wear red as "that is the color a harlot wears". Any sister who wore red was made to feel spiritually weak and would get harassed by the elders. Another thing is they kept a bath towel on the stage so if a sister wore a dress that was too short they should cover their legs up. I'm being totally serious. A FREAKING BATH TOWEL ON THE STAGE!
Another one is no dancing. An elder would walk up to all the young kids in the hall and tell them dancing is "nothing but shaking your sex organs at each other". He was so messed up and gross. I've seen the worst possible examples from dysfunctional JW congregations. So glad to be out!
