This impressive cosplay is by Maid of Might. Here we see more than just fabric being used; there’s actual metal in this costume. Perhaps not quite armour but impressive never the less. It’s pretty uncommon to see lights reflecting in any cosplay. The costume and the photography here are top notch. I’m not sure every convention would let her carry her spear into the building – perhaps that’s why this set was taken elsewhere.
