Fit is by far one of the hardest subjects to address within the realm of manufacturing. There are just so many different body types that it would be near impossible for one manufacturer to address EVERY type in one product—and often times in one line. The most basic body shapes range from round to pear, petite to lean, and every shape in between. When you start to do the math and include XXS – XXL, you come up with a number of patterns that reaches to the Nth power. When you begin to add categories such as Juniors and Misses, it becomes staggering.
Entire classes in design schools and universities around the world spend semesters working on streamlining and finding solutions for fit issues. Body scanners can now take perfect measurements of your body and supposedly create a jean that is perfect for your shape. I find that hard to believe, but based on the shape I have carried with me my entire life, I don’t really care for pants that much anyway.
