Is there more context that obviously identifies it as a Jewish caricature?

I'm pretty sure this guy tried to sell me a moped in Macedonia.

--edit--

Here's Macklemore's response to the accusation:

He explained that he randomly chose the elements of the outfit so that he could disguise himself and move freely around during the secret show.

"I acknowledge how the costume could, within a context of stereotyping, be ascribed to a Jewish caricature," he wrote.

"I am here to say that it was absolutely not my intention and unfortunately at the time I did not foresee the costume to be viewed in such regard."
