Anakin has a made a few mistakes in his career as a Jedi Knight, like when he decided to jump towards Obi-Wan when he had a clear disadvantage on Mustafar, or when he tried force choking his wife, or when he helped Palpatine kill Mace Windu on Coruscant, or when he decided to slay an entire village of Sand People. Hey, not every decision has to be a winner, but at least his choice of clothing was. He successfully made himself look like the coolest Jedi around by choosing some darker colors over the rest of the council. They were kind of a dead giveaway that he was going to turn to the dark side though. It's a wonder Yoda didn't see it coming...

He wears the clothes of Anakin Skywalker before the dark side took possession of him.
