A decorative cover for interchangeable attachment to buttons to change the appearance of the button. The decorative cover includes a base member with a hollow bore extending through at least one end thereof, and a decorative part permanently attached to an opposite end. An inner surface of the bore frictionally engages an outer edge of the button to retain the base member in place but permit it to be removed when desired. In one embodiment the base member is an elastomeric material having a durometer to enable the button to press into an inner surface of the bore. A detent may be provided in the bore to engage the button to assist in holding the decorative cover in place. In another embodiment the base member is longitudinally split into two semi-cylindrical segments that spread apart to enable a button to be engaged between them.
