At the time, my Halloween costumes were usually store bought and relatively simple, although my first five Halloween costumes were homemade by my mother. When I thought of what I had been the year before, an army man consisting of camo patterned long sleeves and cargo pants, I wanted to be something better but nothing on the shelves were worth buying. Transformers had just come out the Summer before, and that's when it clicked for me. I didn't need to buy costumes, I was completely capable of making it (with the help of my dad). I didn't have the time nor any idea how to make it more complex, so I went with a simple shell design to keep it all together (even now I'm trying to think of how I could make it better).
Putting this together is simpler than it looks, to see how I did it, keep reading.
