Just cut out how big you want the ears to be, drape fabric over them, and sew it; you could even stick a headband through them.
A normal martial arts uniform would work; I think you'd just have to make the sleeves and sew them on. :3 Or, you could get a friend to do the sewing, if you don't think you can do it.
