Black Haired Girl Wearing Black Belt Outside On Stairs

In modern times, men started wearing belts in the 1920s, as trouser waists fell to a lower line. Before the 1920s, belts served mostly a decorative purpose, and were associated with the military. Today it is common for men to wear a belt with their trousers.
Since the mid 1990s, the practice of sagging has been popular at times among young men and boys. This fashion trend consists of wearing the trousers very low on the hips, often exposing the underwear and buttocks of the wearer. This urban style, which has roots tracing to prison gangs and the prohibition of belts in prison (due to their use as weapons and devices for suicide) has remained popular into the 21st century, particularly among pubescent boys. A belt may or may not be worn with this style - if a belt is used, it is cinched tightly at the mid-buttock region, with the effect that the trousers of the wearer are being held up by genitalia underneath. Many public schools now enforce belt-wearing, often only for the male population, and requiring the belts to be worn tightly at waist level with a tucked-in shirt.
