The model is my ten year old son.
Step 1: The Breastplate
These measurements I then scaled down to my sons size.
2mm wire is a useful way to capture the unique contours of the wearer
Using those measurements, I fabricated basic frameworks around which to build the armour. Some pieces didn't require this, however, pieces that encircled a part of the body were best assembled around a frame; this helps maintain symmetry. All framework was fabricated from the same cardboard as the costume.
