Wear nothing, let Naal cover you. You two are fantastic together. If you don't go with the Naal coverage I say Kharla should let you look through her closet. I'm sure you can find something suitably sexy/badass in there to put together.
About Chiri, why do you think I suggested the Bondage.Domination.Sadism.Masochism. gear? You would so spank Chiri's ass by the way.
