  1. Measure your waist
    Your waistline is sometimes tricky to find and measure! The natural waistline is halfway between the lowest rib you can feel and the top, outside edge of the hip bone. One trick might help you find this spot are to stand up straight and tilt over like a teapot. Where your torso creases is often where your waistline is. Another trick is just to measure 1” above your belly button.
  2. Measure your hips
    Standing with your heels together, use your measuring tape and wrap it around the fullest part of your hips, including your butt. Make sure the measuring tape is parallel to the floor.
  3. Measure your inseam
    Measure from your crotch down your leg to the bottom of your ankle bone. Inseam lengths in Brooks bottoms do not change from size to size for the same style.
