Why has she got bone boobs?
Practically speaking, she literally has to have bone boobs and flaming long human hair. For much the sane broken, but serviceable cartoon logic of Female Transformers having boobs (which implies the Male Transformers have hidden Robot Dicks).
Female Ghost Rider, PROPER ANATOMY, has flat chest (no mammary glands), wider hip bones, smaller ribcage... Human Skeletons aren't visibly gendered like meaty humans. So you have to play up generic female attributes to sell the
"female" part of Female Ghost Rider. Lipstick on a skeleton would be rather silly. Beyond literally coloring her pink or giving her pink flames, a generic female skeleton looks way too much like a generic male skeleton. I know proper anatomy, you know proper anatomy, but does every other yokel?!? Nope. So even though it's perfectly illogical, dumb, and pointless, BONETITS win.
