As you can see from the above verses Migs, uncovering someone's nakedness was a big no no in the Torah. Those in Jesus' time still lived under the Torah (Law) and I don't think would have brought her to Him naked, as that would have broken the law. She would have been exposed to more than just those who found her. They would have made her wrap herself first, or, she had sex with clothes on... remember that women wore long dresses or robes and I don't know if they wore undies of any sort.
I've heard that Jesus knew their sin and started writing some of their sins in the dirt. Dunno!
