DC Comics

Selina Kyle, better known as Catwoman, first made her comic book debut in the Spring of 1940 in Batman #1. Originally called "The Cat" she began as a mysterious burglar and jewel thief. Her personality as the iconic femme fatale was established even from her very first appearance. However, in the Golden Age, she did not wear her iconic cat suit and actually did not even wear a costume until her second appearance, And even then she donned only a cat mask to hide her identity. Her catsuit did not come into play until the 1960s, and even then it was green, much different than her sleek black catsuit of today.
