What’s wrong with an open collar, especially if Brad Pitt is rocking it? In 1997, Pitt went from a leather jacket to the open collar look. He opted for a slimming gray suit that suits his figure perfectly. He unbuttoned the shirt to make his style pop. This look makes people’s heads turn, though they turn for all the right reasons. He completed the look with leather boots and a big smile (via GQ Magazine).
