A bohemian person lives in a loose, informal way and does not follow the usual rules of “how you should behave” — a steady job, neat clothes, a quiet settled life. Artists, writers, and students have often been called bohemian when they care more about making things and living cheaply than about looking respectable. The word can sound romantic, or a little judging, depending on who says it. In fashion it also points to a mixed, artsy, slightly wild style of clothes. Though actually, it first meant a person from Bohemia, a region that is now in the Czech Republic. English borrowed it from French bohémien, from Bohême (Bohemia). French speakers had used that word for Roma people they linked with that region, and then for artists who seemed to live as free and rootless. So the lifestyle meaning is a later picture, not a geography lesson.
