Abstract: A pneumatically adjustable brassiere re-shapes drooping or small breasts. The brassiere includes brassiere cups of a conventional shape and are respectively composed as an integral body with a first tube made of soft synthetic resin containing a predetermined amount of ceramic material, antibiotics, and deodorizer particles and connected with a feed valve. A second tube is separately connected with an air blowing pump. The first tube has several protrusions for finger pressure therapy and several vents on an inner surface thereof. The feed valve includes a valve sheet for intake of air into the valve body with alternately opening inflow holes on the valve body, two highly elastic springs and corrugated air pumps to vibrate up and down according to a wearer's movement so as to automatically supply air to the first air tube.
