Black has been a fashion hit since, well since forever. But when we are talking about witchy fashion, it would almost be a sin not to wear something that just screams darkness. Be careful, however; not even witches are allowed to wear all black, it sure is fun to combine it with some other mysterious colors. My personal favorite being dark green and gold, however; you can go wild with any color of your choice, just remember the lighter and more vibrant the color is the less you should use it. For example, a big golden belt is okay, but when in comes to yellow, try staying humble, and just wear some earrings or similar.
