i recently made this tunic for aaron, to wear at pennsic. it's basically a djellabah (did i spell that right?)
it has a HUGE neck opening that extends halfway down his chest so that he can drop it around his waist and knot it up and have a kind of sarong/skirt thing going on if he wants to otherwise it's just a big loose tunic and he can attach a button if he likes to the opening to keep it from gaping
