Costume Black Boots - So, I swear to God, I have a pair of black patent leather boots from prowrestlingboots.com that cost around $200 that I said "I'll wear after those $50 costume boots bite the dust"; a year now and these cheap costume boots are still going strong - a couple of the guys I work with bought a pair and swear by them too for the price.
Stock Kick-pads from elucha.com - They don't sell the design I have anymore, but it's a white skull with silver revolvers crossed underneath
Silver star kneepad covers from elucha.com
ASICS Kneepads
Liquid latex body paint for face paint

Pics with/without kickpads

Hope it gives you some ideas.
