Selina has had a long evolution of costumes and origin stories ~ and at the height of the Comics Code era in the 50s, she was mostly written out of the series (like the Joker) for being too sexual and more than somewhat fetishy.
Fortunately she made a comeback in the 60s and it's been all stilettos and leather whips since. One of her most recognizable outfits, however, is one of her oldest: the wholly impractical purple gown (harkening back to the 40s), with a green cape (purple and green were common "villain" colors.
Anyway, after some very far out outfits in the 60s (which we will likely get to at some point), Catwoman returned to this classy look for a good spell. The 80s would finally put her in something slightly more practical, though 100x more sexualized ( with a tail no less). These days, while still sexy, much of her outfit is functional and a pair of goggles are common headgear along with her cat ears. But it's this initial outfit I have chosen for her first plate because even though it came from the 40s, it was common in the Bronze-Age.
Also, in keeping with the Nolan's Dark Knight Trilogy theme, I have given her the likeness of Anne Hathaway who played her in The Dark Knight Rises.
You're probably not keeping track, but yes, I did skip two Batman plates (9 & 10). I'll get back to them in a bit. I just realized I still have characters I haven't posted!
