Every detective, undercover agent and steampunk adventurer needs one detail that sells the role, and this shoulder holster costume delivers it. The black leatherlike holster sits across your shoulder and instantly turns a plain shirt or vest into the outfit of someone who means business.

Men and women alike can gear up for Halloween, cosplay meetups or a cops-and-robbers party. Add goggles and a waistcoat for a steampunk twist, or team it with the captain of the sea costume, a pirate sword and a buccaneer pirate gun for a high-seas captain with a serious edge.

This shoulder holster costume piece is sold individually, so pick one up for each member of your crew and call the case closed.
