Auditions will never under any circumstance, cost you any money EVER. Casting directors are paid a set fee from the production to cast their projects. An open call, an opportunity you do not need an agent to do, should never cost you any amount of money.
Can I wear jeans to an audition?
You don’t need to dress like you’re going in for a corporate interview here. Your clothes shouldn’t be a wrinkled mess, but you also shouldn’t be wearing business attire to an audition. A good pair of jeans can go a long way, and it’s worth investing in a pair for auditions alone.
