premise: Khaki pants with wide waists and short inseams have more variable demand . 
hypothesis: A successful U.S. apparel-maker , for instance , may assemble basic men 's khaki pants in average sizes in Mexico , taking advantage of low labor costs as well as Mexico 's proximity to the maker 's Texas distribution centers ; at the same time , this company can choose to manufacture products with more variable demand , like khaki pants with narrow waists and long inseams , in the United States , providing fast turnaround for retailers and lower exposure to inventory risk .
