I just wanted add all the specific pieces since it had not been done yet, taken from Xbox 360 achievement guide written by OG T UNIT.
For this you need to find all the materials required, along with the pattern. Details below:
-Pattern is found within the chest that is in the maze type area, opposite the 'Secret Cave'
-Track Suit is found in a cave, south of the first bridge in the game, you have to jump down and follow a series of planks to get to it.
-Wire Mesh is found within the cave that you need to use the grapple hook to get to. The line is just before the cave where the Track Suit material is found. (If you are lost then look for the maze before the green river at the start of the DLC. Take the route that hugs the river then use zip line at end of that. -The Yiddler *Thanks!*)
-Crepe Paper is found after the first bridge, just follow the southern fence until you reach a gap, just drop down and it's in the chest on the same platform.http://www.xbox360achievements.org/game/costume-quest/guide/
