early 13c., "characteristic attire of a religious or clerical order," from Old French habit, abit "clothing, (ecclesiastical) habit; conduct" (12c.), from Latin habitus "condition, demeanor, appearance, dress," originally past participle of habere "to have, hold, possess; wear; find oneself, be situated; consider, think, reason, have in mind; manage, keep," from PIE root *ghabh- "to give or receive."
Habit is a custom continued so steadily as to develop a tendency or inclination, physical or moral, to keep it up; as, the habit of early rising; the habit of smoking. Habit and practice apply more often to the acts of an individual; fashion and usage more often to many .... [Century Dictionary]

In 19c. it also was used of the costume worn by women when riding on horseback.
