Preparation:
1. Have two identical sets of clothing, one set worn under the other. The outer clothing should have a jacket or cape that can easily be removed.
2. Place the second set of clothing nearby or have an assistant ready to hand it to you during the trick.
Performance:
1. Establish the trick: Begin by showing the audience the outer set of clothing, ensuring that they can see all of your limbs and that there are no obvious hiding places.
2. Cover up: Hold your jacket or cape in front of your body, creating a barrier between the audience and your clothing. This is done to conceal the removal of the outer layer of clothing.
3. Quick change: While the jacket or cape is held up, quickly remove it and pass it behind you. Simultaneously, grab the second set of clothing from your assistant or retrieve it from your hiding spot.
4. Reveal the change: Bring your hands back in front of you, dropping or throwing the outer clothing to the floor. This creates a moment of misdirection and distraction, as the audience's focus shifts to the jacket or cape on the ground.
5. Showcase new outfit: Lift your arms to reveal the new set of clothing, showing the audience that you've changed clothes in an instant.
6. Take a bow: As the audience reacts, take a bow or perform another flourish to complete the trick.
Remember, the key to a successful quickchange magic trick is practice, timing, and precise coordination between your movements and the reveal of the new outfit.
