Hi Sonicturboturtle,
As said by "dannydizzo" there is no "Special" type of clothing requirement.This is 100% sleight of hand
It uses a normal/ ungimmicked coin and thats it.
but in few of the vanishes you would require a clothing requirement (Not a special clothing requirement)for the proper ditching of the coin.
In every vanish you will learn a new move/technique to vanish as well as ditching of coin to end totally clean.
Let me know if you have more queries..
