20th century bra, 18 inches.

The magician ties two handkerchiefs together and puts them around the neck of a spectator.

After making a silk scarf disappear, he pretends it reappears between the two tied handkerchiefs. But when he pulls the handkerchiefs apart, a bra appears!

• The polyester handkerchiefs are 18 inches long.

• The trick includes everything except the small silk handkerchief, which must disappear (use your preferred method to disappear).
