/cgl/ - Cosplay & EGL

hello /cgl/ i seek help on costume ideas, since im overweight i always build big bulky armor suits and such using the pepakura method i've pulled an Alphonse Elric and made a warmachine suit for a friend but i have no idea on what to do next, someone i know can make metal weapons like swords or axes and such and told me he could make me one as long as i bought the materials (roughly $50-100) but i have no idea on what to do next.

I was thinking of making a Cyan Pile armor and get the sword but im not sure, if anyone has an idea im all ears
