The paldron is actually more complex than you may first think. It's even more then three sections. I've been researching this for myself and have found the Jedi paldron to have 11 sections!!!
You have the center piece for the chest, then one for the back. Two strips either side of these for both front and back. Then two more strips on the left and two on the right. Then the neck ring/collar to complete it. All of these sections are joined by some sort of elastic material. Every section moves freely with the characters body movement.
I modelled a solid one piece in 3D which I think is wearable though it will probably restrict movement but will give you the look of the Jedi armor. I will be working on a more complex multi part version at some point in the future too. With the 3D model I create templates to make them using card and fibreglass or sintra.
Here's a pic of the one piece I did:
