I did see Jacqueline Suzanne walking near Central Park in the early 70s She looked like a caricature: fancy hat, large white fur, thin skirt—led by her poodle down the sidewalk.
It was almost cartoonish. Truman Capote may been a bit strong with his description but he was not far off.
She was a woman “of a certain age” at the time, and, it seems, very ill. Its a bit pathetic what a formerly beautiful woman can be reduced to when time turns against her.
I have seen a few cases.
