Paris ls Burning
When I used to live in south Florida, we had the Witch of Wellington.
She was an older woman who wore all black. Her wardrobe consisted of long dresses that covered all her skin, high platform shoes, and interesting hats.
She was about 7 feet tall (once you figured in the shoes and hat) and extremely thin and she didn't walk, she shuffled slowly.
She didn't drive, so she could frequently be seen walking around and she went to Walmart on a regular basis. She's all over peopleofwalmart.com.
That sounds like a woman that used to scream religious phrases at people around my step dad's restaurant...she wore a long black dress but wore a long white shirt that advertised a church. She died though..
@OP there are too much for me to list
