Although dimensions vary somewhat among clothing manufacturers, a typical size 14 in women's clothing measures 40.5 inches at the bust, 33 inches at the waist and 43 inches at the hips. For J. Crew, this is a size "large."
Although these are the dimensions for 2014, measurements are quite different from even a decade ago. Many clothing manufacturers use "vanity sizing." Sizes are dropping so consumers feel better about buying garments. Overall, the size of women has increased since the 20th century. Measurements of sizes for sewing patterns have remained the same for decades, and a comparison shows how sizes of manufactured clothing have been reduced. A pattern for a garment with 30-inch waist and 40-inch hip measurements is a size 16, but at J. Crew, those measurements equal a size 10.
