A breast prosthesis is provided for women who have undergone a double (or single) mastectomy. The prosthesis comprises a breast form that substantially resembles a human breast and a back panel to which the breast form can be coupled. The breast form has at least one magnet adjacent a wearer's chest when the prosthesis is worn. The back panel also has at least one magnet that faces outwardly from the chest when the prosthesis is worn. When a wearer wishes to don the prosthesis, she places the back panel against her chest in a desired location, with the magnets facing outwardly. A garment may then be placed over the panel before the breast form is placed over the garment. The back panel and the breast form may then be coupled to one another via their magnets (which attract one another) so that the prosthesis is secured in a desired position.
