I'm glad that us Kats aren't being an obnoxious mess about this and denying that Katy wasn't inspired by Katy Keene, and we are able to make jokes about the comparison (rather than excuses)
No one will care because I think to an extent we all know Katy isn't original. She knows she isn't an innovator and knows her lane. It's like when she stole Roar from Sara, no one made a huge stink.
In the book From Girls to Grrrlz: A History of Women's Comics from Teens to Zines by Trina Robbins Katy Keene is called a Bettie Page look-alike. "... but the resemblance ended there. Katy Keene was no bimbo and she had a good job (she was a movie star.)"
