Quick test before you read another word. Picture Tom Cruise in Risky Business. The scene. Parents out of town, socks on hardwood, Old Time Rock and Roll. What is he wearing?
You said a white button-down shirt and sunglasses. Almost everyone does. The shirt in that scene is pink, and there are no sunglasses in it at all. Go look. We will wait, and we will still be here when you come back needing to sit down.
