Shirt Tails
The Shirt Tails were a mid-19th century street gang based in the Five Points slum in Manhattan, New York, USA, who wore their shirts on the outside of their pants as a form of insignia and as a sign of group affiliation. Members kept their weapons—as many as three or four at a time—concealed beneath their shirts; this discreet measure stands in contrast to competing gangs who flaunted their weapons in order to intimidate.
