Stand up straight with feet flat on the floor, arms relaxed at sides. For accuracy, measure over undergarments & keep the tape measure parallel to the floor.
Measure around the fullest part of the chest/bust, while keeping the tape under the arms and around the shoulder blades.
Bend to one side to find the crease of your natural waistline and measure at that point, keeping your measuring tape comfortably loose. If you are between sizes, order a size up.
Measure around the fullest part of your hips, 7-9 inches below your natural waistline.
Measure similar pants that fit well. Lay them flay with the front and back creased smooth. Measure from the top of the inside seam to the bottom of the hem.
Dresses are measured from the highest point of the shoulder to the bottom of the hemline.
Size charts are to be used as a guide and provide general body measurements. Sizing and fit may vary by brand and/or body type.
