Bra Trick

From MagicPedia

The Bra Trick also known as "The Baffling Bra" is an comedy effect created by Howard Brooks based on the Twentieth Century Silk effect.

Effect: The magician ties two silks together and asks a female spectator to place them down into the top of her blouse. He then makes a silk disappear and states that it will reappear between the two tied silks. With a flourish he pulls the silks out and displays them, but tied between them is a bra.
