Abstract: A bag holder (650) for holding a t-shirt bag (651) includes a holder frame (652) and a holder handle (654) that is secured to the holder frame (652). The holder frame (652) selectively holds the t-shirt bag (651) and including a first handle restraint (658) that restrains a first bag handle (651B) of the t-shirt bag (651), and a second handle restraint (660) that restrains a second bag handle (651D) of the t-shirt bag (651). The holder handle (654) is movable relative to the holder frame (652) between a carrying position (678) in which the holder handle (654) is used for carrying the holder frame (652) and the t-shirt bag (651), and an attachment position (680) in which that holder handle (654) is used for hanging the holder frame (652) and the t-shirt bag (651) near a vertical surface (676). With this design, the bag holder (650) can easily be carried and moved by hand, and the bag holder (650) can be easily secured to a door (686).
