For me, physical features do not add to the ability of a person in doing magic. A kid can do better magic tricks than an adult or an Asian magician is always the best. Physical aspects of a person should never be a basis that he is a good magician.
But if you want to look more likely a magician, you can wear something that will make you look like a legit magician. Magicians usually wear black clothes, this is to have a mysterious aura. You can also wear silver accessories like rings, bracelets or earrings. If you aim to be known to be a dark and mysterious magician, save your smiles to the cameras and perform tricks with a straight face.
