Because I can't be here for the costume contest this weekend, I'll pop a couple of power-suit outfits up to inspire you all.
On the left, Veritas Ex Machina and on the right Johnny Rocketboots.
The idea with Veritas Ex Machina was to put as many angular pieces on one costume as I could.
The idea with Johnny Rocketboots was to light him up like a Christmas Tree. Colours inspired by some other game - possibly Wildstar.
... and if it bothers you that Johnny Rocketboots uses a jetpack and not rocket boots, haha the joke's on you, I don't care!
