An adjustable garment hanger comprising of a frame depending from a hook is disclosed. The frame is comprised of two inclined arms intersected by an optional cross bar. Within each inclined arm is an integrally formed locking bar that extends from the integral base to a free distal end. Each locking bar includes notches and a pushbutton at the distal end. Ribs that form channels and that may form ramps are disposed on the sides of the inclined arms. Movable covers having internal ribs slide onto each inclined arm while the internal ribs engage the ramps, channels, and notches. The ribs when supported by the ramp causes the outer ends of the covers to be tilted upwards. Other ribs located on the covers engage the notches of the locking arms thereby fixing the relative extended or retracted position of the covers to the inclined arms. The locking arms are biased outward away from the frame thereby placing the notches into engagement with the ribs of the cover. The locking arms can be disengaged from the covers by thumb or finger pressure on the pushbuttons. The adjustable hanger frame has a T- or I-shape cross section.
