I guess he can dress as he wants considering he's making $24M/yr. Money can buy almost anything.
Example. Wife told me this story today...
She was treating a patient and he had a friend in the room with him. The patient asks my wife, "You married?". Wife says "Yes. Why?". The patient said his friend was worth millions and was looking for a wife.
My wife's reply... "Let me think about it.".
I told her to call in sick mañana.
