You’ll want to wear close-fitting clothes so that loose fabric doesn’t get in the way of measuring. If you’re at home or in the privacy of a dressing room, measuring in your underwear is great.
Measure your chestWith good posture, wrap a measuring tape under your arms around your back and take the measurement at fullest part of your chest. Be sure to keep the measuring tape parallel to the floor.
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.
