This is a LoRA model of Karen from the anime Sky Girls.
I'm actually surprised by how well this turned out, as there really isn't that much fan art of Karen available (with me using screencaps as well) to make it.
To create her regular attire, use the following prompts: karen sonomiya, grey hair, long hair, low twintails, hair ribbon, bare shoulders, pilot suit, solo, elbow gloves, orange leotard, halterneck, orange thighhighs, headgear, small breasts, purple eyes
Art based on the coloring of the "First Draft Style" figure released in 2008 is also possible. Just used grey leotard, grey thighhighs, and grey headgear in place of the orange items (while adding a negative prompt for purple headgear, as it tends to show up if grey is being used instead of orange).
