A versatile individual who doesn't fall into a particular group. Whose sense of style can't be charactorized. She or he instead chooses to mix up their choice of clothing. One day may be referred to as a hipster. Next day may be referred to as a hypebeast. But, is neither. Instead she/he is a mixter.
Him: Yo, wassup with you? One day you're wearing a BBC shirt and looking all hypebeast. Then the next day you're something vintage and looking all hipster. Make up your mind. Which one are you?
Her: Neither. I'm a mixter.
