Z!
A master swordsman and horseman who defends against corrupt tyranny, this gracious and masked nobleman is legendary... and so can your presence in the party be in a Zorro costume.
Your enemies will be shaking in their boots and the ladies will be shaking too.
Black everything: shirt, pants, belt, boots, cape, half mask, bandana and gloves. Paint or grow a neat black mustache. Nice props for a Zorro costume would be a black spanish hat, a fencing sword or a bullwhip.
Go whip up some fun!
