The body fan device comprises an outer casing having a front side and a rear side with the front side directed toward the user and the rear side directed toward the garment. A fan is mounted between the front side and the rear side. A power mechanism powers the fan. A securing mechanism secures the outer casing between the garment and the user. A front vented panel is mounted to the front side of the outer casing and a rear vented panel mounted to the rear side of the outer casing. Upon activation of the fan, air is drawing through the rear vented panel inward into the outer casing and out through the front vented panel and against the user.
