How to Find the Right Jean Size For Your Body Type, According to Madewell's Designer

"Your waist at its narrowest part should indicate the measurement that correlates to your jean size. Even though that should give you a good idea of your size, all body types are a bit different, so I recommend you order two pairs to test out. For a stretch jean, order the size that your measurement indicates and one smaller. For nonstretch, go the other way and order your size and one bigger. It's always best to go to a store if you are new to a brand and try on different styles and sizes."
