Here are the ones that I can think of right away:
We were never allowed to wear denim skirts to the meeting. It didn't matter if they were modest, just the fact that they were GASP....DENIM, made them inappropriate to wear to the hall. I had an elder's wife corner me in the hall when I was 10 yrs old or so and give me a 15 minute lecture about how disrespectful my denim skirt was.
Also, we had a CO for a few years that would preach from the platform that sister's skirts should be AT LEAST two inched below the knee, no shorter. He preached it like it was written in the Bible somewhere!
And last but not least, the JWs I knew sometime preached against songs that "sounded" demonic. Their lyrics might be OK, but by god, Satan was trying to stumble you with it's demonic sound!!! When I was a teenager, I was into Alice in Chains, and I especially liked that song, I stay away, if anybody here is familiar. When my mother heard the "demonic sound" of that song, she comfiscated my CD and tossed it in the trash.
