AFIAK, the markings that are on her now are fairly accurate. I've also heard the story of the girl being nekkid when she was in combat, but like Stangdriver said, it's only anecdotal evidence, with no photos to back it up.
Here's the best pic I've ever found of SB in her original markings (unfortunately, it doesn't show the nose art.) The NMUSAF has duplicated the markings pretty faithfully.
Here's the only wartime shot I've ever seen of the actual artwork. It's actually much more profesionaly done than the current nose art..which is rather crude and cartoony.
