Cary Grant and the Summer Suit

It's clearly summer. He's tanned, and his shirt is therefore white, to show it off all the more. His suit, even, moves to the lighter direction, as does his tie. Flusser thinks that keeping a similar shade throughout an outfit looks modern. I agree, and Cary grant looks modern, even in black and white, gray and white, really.
Look at the details. The tie dimple. The rumples in the suit sleeves. The way the collar shows itself, the roll of the suit collar. The hint of a pocket square. The tie is woven enough to show. It's a simple look, surely. One wonders if the jacket is a suit or a sport coat. I think it's a suit, but that's just my suspicion. It could go either way.
