Measure around fullest part of your chest (usually at the nipple). Hold the tape sufficiently easy -allow room for one index finger between the tape and the body. Keeping tape up under armpits, and make sure that it is centered well over shoulder blades in back and over fullest part of the breast in front.
Measure around your body, where your belly is. Hold the tape sufficiently easy -allow room for one index finger between the tape and the body. Thin people should measure at their thinnest point and large people at their widest.

Measure your body from one armhole to other armhole at back.
Stand with heels together. Measure around hips at widest point of seats. Hold the tape sufficiently easy - allow room for one index finger between the tape and the body. Make sure your trouser pockets are empty before applying the tape measure.
