The smart-casual trouser emerged as workplace dress codes relaxed in the 1990s and 2000s. The challenge was a pant that reads as professional at first glance but is comfortable enough for a long day. Custom-drafted with extra thigh room for athletic proportions, there is space to move without looking baggy at the hip.
