Clint cleaned up nice when the situation called for it. Granted, he didn't particularly like suits, but he knew what worked on him and what didn't, which was why he knew that dark colors and simple lines were his best bet.

Even his mask was simple, basic black, asymmetrical but stylized that way so it didn't just look like he'd put it on crooked. He was keeping an eye on things, as he was prone to doing.
