Pass the tape measure around your body at your waist. Take the tape measure straight across the navel/bellybutton completing a circle around your body.  

Although many of our pants sit low on the waist or even the hips, the measurement guidelines are from the waist.  

All garments run true to size except where the descriptions indicate a generous/oversized style. In these cases, you may wish to order a smaller size. You may also wish to order a smaller size if you prefer a more form-fitting garment.
