I Spy

I'm auditioning for a short film called "I Spy " at UH this Sunday for the part of a young, Asian security guard turned spy. Does anyone out there want to help me rehearse my sides? That's showbiz lingo for exceprts from a script. How does one dress for as a security guard? I'm guessing blue shirt, black tie and slacks. That's kind of cliche, but it's all I got.
