All I did was go out to TKMaxx and find some green trousers/jumper which vaguely look like the equalists sort of clothing. Then i got a black shirt to go underneath (incase i got too hot). Went to John Lewis (big aparment store) to get some burgandy fabric for the shin/arm/elbow/trousers part of the costume. Found a wide belt from...Primark I think it was (and gloves)
The goggles I got from online - not sure on the store, but if you just google Green steampunk goggles you can probably find them.
The "hat" is just a balaclava with spare fabric sewn on (my current uni flatmate is doing fashion so i just borrowed some off her)
and that's all I think....oh and I hand sewed everything because I don't have a sewing machine.
