Snapping their heads from side to side, marching into the roads in close-fitting blue uniforms and black heels, the "traffic ladies" who marshal vehicles at the intersections of Pyongyang are an emblematic image of the North Korean capital.
Officially known as traffic security officers but universally referred to as traffic ladies, they are chosen for their looks in a society that remains traditionalist in many respects.
They must leave the role if they marry, and have a finite shelf-life, with compulsory retirement looming at just 26.
The 300-odd ladies are unique to Pyongyang, which North Korean authorities are always keen to present in the best possible light despite their nuclear-armed country's impoverished status, and ensure a steady supply of photogenic young women who are the favourite subject of visiting tourists and journalists.
No age limit applies to their roughly 400 male counterparts - who tend to be stationed at roundabouts.
The rules were because "normally, the women in our country marry at the age of 26 or 27", explained the officer, who did not want to be named. "Because the role is tough and difficult, they can only do the job when they are single."
