This was a "happy accident" as Bob Ross would say. I was just goofing around and clicked on the Spider-Man costume someone made. For whatever reason the Spidey costume mesh overlaid itself onto the skirt that the generic character was wearing. I just thought it looked neat.
I'm not sure if a female Spidey character in the comics has worn a skirt before. The face and hair were just whatever the generic character came out with. There is a Spider-Man mask to match but I like it better without the mask.
