I never saw Jan Crouch in a pink wig, only light blonde. She’s the wife of the founder of TBN. She is a Pentecostal Word-Faith believer IIRC. It’s a big movement. She wears big wigs because she likes them. Some are humongous. They’re all different shapes.
TBN airs everyone from Billy Graham to John Hagee to Joel Osteen, in that range, the Bakkers used to be on, they air PTL too.
Tammy Faye Bakker dressed as she did because she wanted to prove a Christian woman needn’t go around in long gray denim smocks and faded turtlenecks with little teddy prints all over them, no makeup, no jewelry, dark blue crew socks and brown clogs, or any such style, which is how many believe they have to look. So she dressed all the way to another extreme to make a point of it, so no one could ignore the makeup and jewelry. She knew she looked unusual, but to her it made sense.
