Uniformed officers PC 220 and PC 601 start out in modern police uniform with pristine white shirts, smart black combat trousers, and chequered cravats, and black wellies. They don full suits of Regatta rainwear, and then they drench each other in mud to see how well the rainwear performs.
Once both are completely covered in mud, including lying on the floor and pouring it over each other's suits, they cut and rip the rainsuits off each other to see how well their uniforms have been protected. The answer is not all that well, so they sit down and shred the rainwear completely, getting an awful lot of mud all over their trousers in the process. Then, as their uniforms are already mucky, they finish them off completely, pouring mud into each other's trousers, all over each other's shirts and cravats, and eventually all through each other's hair too.
Now that's how you test a uniform!
