For sisters, it was all about the skirts. Way back when, one sister told me that one of the elders had them come up to the stage after the meeting. Why? He had them get on their knees to see if the skirt touched the floor.
Denim skirts came into fashion for awhile. They were comfortable and easy to wear. Didn't have to dry clean them either. Next thing you know, NO DENIM skirts. They were "too casual" to wear to the meetings.
After years of the WT worrying over skirts being too short at the knees, they attacked the long skirts. My sister was told that hers was too long and had her shorten it. (she regrets that to this day)
Have a below the knee skirt? You might have the dangerous slit up the back (or side) of it that might show too much thigh. Sisters pinned it lower down or like I did, made sure your slip was lower.
There is also the crazy people in the hall that wanted their own rules followed. One sister had a small hair clip with a dragonfly that slightly bobbled when she moved her head. She was counseled that it was too distracting. (brought up by a crazy old lady)
Of course there was the infamous mirror covering that went on at conventions years ago. You don't see it now but they covered them up to keep sisters and brothers from standing in front them, fixing their hair or makeup. Turns out my sister and another one, marched up to the convention leaders and said how are we supposed to know if a baby has barfed on our clothes, or if there is food stuck in our teeth? Etc. Down went the coverings. Ridiculous isn't it?
