For a school assignment we visited http://itscharacterdriven.blogspot.com/ and used their random character generator. It generates physical descriptions as well as personality traits.
My randomly generated concept was:
A kind gawky lover who may or may not be a genie.
I went with the original Arabian concept of the genie/djinn as a race of people from a parallel world, rather than the modern idea of them as strictly wish granting servants.
Here are a few of the concept sketches done for the assignment. I looked at a lot of traditional Arab clothing as well as some corny halloween costumes and movie wardrobes.
