Describe Paul's physical appearance in court.

From the text:

Paul entered the faculty room, suave and smiling. His clothes were a trifle outgrown, and the tan velvet on the collar of his open overcoat was frayed and worn; but, for all that, there was something of the dandy about him, and he wore an opal pin in his neatly knotted black four-in-hand, and a red carnation in his buttonhole.
