All clothing lines have a unique fit and the term “Standard” U.S. sizing is a misnomer. That is why we offer several fit tools on our website to help you determine your correct size. The first is our detailed size chart that uses your waist & hip measurement for pants and bust measurement for tops. Our detailed sizing chart can be found on each product page. The second is called Fit Finder, you can find more information about this by clicking on the View measurements link on each product page.
