But back in the 70's and into the 80's, the Maid of Might had a 70's style that didn't carry the taint of the bell-bottom and platform shoes look. I have no idea how the choker cape worked, and the S-shield becoming a patch was probably a mistake, aside from the obvious benefits of the V-neck blouse. She briefly had those strappy Wonder Woman shoes, but eventually switched to the classic M-top boot.
