Ripton Apparel Size Chart
True Waist: The narrowist part of the torso. Just under the ribs.
Hip: Widest part of the hips/butt
Remember that Ripton Jorts are made from a thinner technical denim than other options. This means they break in to your body more completely. Give them 3-5 vigorous wears without washing to let them settle into their proper shape. If they fit your waist ok but are tight on your legs, they will stretch in nicely.
