Final answer:
During World Wars, society women in London would stand on street corners to shame young men not wearing uniforms, reinforcing military service expectations.
Step-by-step explanation:
During the time of war, especially the First and Second World Wars, society women in London and other parts of the United Kingdom played a unique role in enforcing social expectations related to military service. These women would often stand on street corners and publicly shame young men who were not wearing uniforms. This was because soldiers on leave were required to wear their uniforms so that Military Police (MPs) could easily identify and regulate their behavior. Men who were out of uniform might be suspected of evading these regulations or shirking their duty to serve. Civilian attire could be obtained by servicemen through underground "locker clubs." These societal pressures reinforced the value placed on military service and the expectation of visible participation in the war effort.
