After dueling with Handmaiden, she is not wearing anything. Put some clothes on yourself then ask her to put some clothes on. The robes she puts on are valuable. You can repeat this process as many times as you desired and sell the extra robes. Note: Only Handmaiden can wear these robes. Additionally, after sparring with the Handmaiden, tell her to put some clothes on. Make sure that you also have clothes on. She will put on her mother's Jedi robe, which only she can wear. It gives a +3 bonus to Defense and a +2 bonus to Charisma.
