Sorry for the late reply. I think the show's staff were intending on having Lu topless, as seen in a pre-production image that was shown in the October 1999 issue of Disney Adventures (seen here) as well as an issue of Animation World (with the characters arranged in a different order.) There may have also been plans for Og's loincloth to be backless, as depicted in the "Crash Lancelot" pilot.
