In a growing online denim market, smaller women’s sizes command the largest prices

While in store purchases may be distressed, online jeans sales grew 28 percent from 2014 to 2015, with sales peaking in November in both years.

The top ten online denim retailers saw sales increase between 15 and 56 percent from 2014 to 2015. Nordstrom.com and Gap.com experienced the most sales last year, and Nordstrom posted the biggest gains in the group, at 56 percent, followed by Levi's.com.

In the course of our analysis, we uncovered an interesting trend: women spend more for less denim; indicating that women may pay more on smaller-sized jeans. Women spend an average of four dollars more per pair of jeans than do men, but their average spend increases dramatically for smaller sizes. The average price of women's jeans is $48, but the average price nearly doubles for sizes that are 24 inches and smaller.

While the average American woman has a 34-inch waist, according to researchers with the American Medical Association, 28-inch jeans are the most popular denim size online.
