Abstract: A portable dressing room assembly includes a support frame including a rectangular base portion and a rectangular top portion. A plurality of vertical sections is removably attached to and vertically separates the top portion from the base portion. A support dome is removably positionable on the top portion. A flexible covering is removably positionable over the support frame and the support dome. The covering includes a top wall and a peripheral wall that is attached to and extends downwardly from the top wall. The covering has a size such that a bottom edge of the covering is positioned adjacent to and extends along the base portion when the top wall abuts the support dome. The peripheral wall has an opening therein defined by a flap for selectively accessing an interior of the covering.
