@jmars,
iF YOU COPY SOMEONE YOU MAY BE IN BREACH OF COPYRIGHT LAW OR TRADEMARK LAW.
some performers have copyrighted their "look".
Copyright applies to any expressible form of an idea or information that is substantive and discrete and fixed in a medium. Some jurisdictions also recognize "moral rights" of the creator of a work, such as the right to be credited for the work. Copyright is described under the umbrella term intellectual property along with patents and trademarks.
