Alice Kramden from Jackie Gleason and the Honeymooners (1956) by DC Comics. Fictional character trained only on the comics. No TV show or live action images were used. Does not resemble or represent any real person.
No default costume. They dressed her sexier than the TV show, but still appeared a lot with the stereotypical 1950s dress and apron. The black shorts and striped shirt combo appeared multiple times and was the closest to a default costume, even if it was supposed to be her beach outfit.
