This is far and away one of the most complex cosplay costumes I’ve ever seen. Its the Shiva Sisters from Final Fantasy XIII, and I’ll just let the designers explain how they made it:
“I made the jumpsuit in actionwear and attached navy fleece-backed pleather on top. The “wings” are pleather with a wire frames to make they stand up. The armour is mostly made with styrene and lined with foam, camping/yoga mats. The seat is made entirely of foam. The feet are made with styrene and plastic bottles.
Claws are wonderflex. All small detailing were sculpey and light sculpey. All the chain was made by hand then spray painted gold. The headdress is also made with styrene and foam. It is lined with wire to give it shape. It has a piece of wood along the centre for stability. The handle bars are straws and pixie sticks. The clear top is black sheer vinyl. The wheel is foam, the spokes are wire and straws, and pixie sticks. The headdress is held on by one black strap under the chin.”
