Pants sizing varies from one designer to another, but most base the sizing on waist, hips and inseam measurements. When shopping for pants online or in a store, it is best to know these measurements to compare them to the store's sizing chart.
In the 1940s and 1950s, there were U.S. standard clothing size charts developed based on statistical data, but these have changed over time. In 2014, the various U.S. clothing size manufacturers take height under consideration as well. Each clothing company has a different sizing scale.
Some clothing categories for women include Misses, Junior, Miss Petite, Junior Petite, Young Junior and Women's.
