背心变色-M

The magician is seen wearing a normal vest, buttoned at the front and worn showing out from under an open jacket. The magician turns to his table to take a prop from the table top. Upon turning back to the audience the vest is seen to have changed color.

This is repeated once more later in the programme, and a third time. This not only stands as a unique quick change effect on its own, but also may be performed as a novel running gag which may be repeated ad infinitum throughout a show.
