I *think* it would be something along the lines of 彼は何を____いますか。but I am confused because it is my understanding that 着て applies to things put on the body, はいて to the legs and かぶって for the head, right? (Please tell me if i'm wrong!) so what word would be appropriate to ask "what is he wearing?" in general? Thanks in advance ^.^
