Spandex Tights - Adventures of the Aerobic Duo
This pair started out in the 80s (when else could it have been?) as Lycra Woman and Spandex Girl but the creators had to call back and destroy all the original copies because DuPont owns the name Lycra and would not let them use it, for some reason they had no problem with Spandex. So they changed her name to Flex Woman and returned in the 90s.
