Garibaldi's Redshirts.
Giuseppe Garibaldi (1807 - 1882) was an Italian folk hero, a nationalist in favor of Italian independence from Austrian domination. Garibaldi's "total sincerity and honesty, and exceptional physical courage gave him the kind of personal magnetism which made women of all classes love him, and men of all classes follow him in circumstances of acute danger." During the Expedition of the Thousand campaign in 1860, his volunteer followers were known as "Redshirts" ("Camicie Rosse" in Italian) for their uniforms (or rather shirts, as they could not afford full uniforms), and it is these who inspired the fashion.
