When Gracie is in the dressing room getting ready to go on stage in her swimsuit, Victor comes in with stuffing for her bathing suit. Gracie is rapped up in a towel and Victor says, "open up."

When she does you can see in the mirror that her sash is not in the middle of her chest. But then they show the FBI people watching her from the camera that is reflecting from the mirror. Now her sash in right in the middle of her chest. I think this is a slip up.
