What about the possibility that in that picture of Diana, Mary and Flo with the "different" wigs on that they were in wig shop trying on different styles? Clearly, Mary is trying on a wig [[she's holding a hand mirror and looking doubtful), Diane's trying to adjust it and convince Mary it looks good on her, and Florence is laughing--probably because Mary is clearly convinced that is NOT the wig for her. Seriously, though... I don't think Diana is "wearing Flo's wig"--when have we seen any other pictures of Florence wearing that color wig in that style? I vote for that pic being from a wig shop visit or the wig department in a department store [[Saks Fifth Avenue in Detroit?).
