Step 1: Cans
At first you need a lot of cans... about 350-400!
I decided to use RED BULL COLA cans because of two reasons.
First one: i like the colours and their combination in this diagonally way.
Second one: some cans are made out of aluminium, others are produced out of tin-foil (coca-cola). Red Bull uses aluminium. The advantage of aluminium is, that you have no corrosion (rust) at the cut edge and its much easier to cut and to punch!
The disadvantage of aluminium is that its not that ductile, tin-foil is more ductile, and therefore it breakes easier when you start buckling it 2 or 3 times at the same place... but if you act carefully with your suit, this won´t be a problem.
The gloves for this suit aren´t part of this instructable, they have their own and can be found here: http://www.instructables.com/id/LED-Gloves/
