Quick answer: Measure your chest, waist and hips correctly so you can compare your body measurements with clothing size charts.
What you need
Use a flexible measuring tape, a mirror and close-fitting clothing. Ask someone to help if you find it difficult to keep the tape level.
How to measure your chest
Wrap the tape around the fullest part of your chest. Keep your arms relaxed and make sure the tape stays horizontal across your back.
How to measure your waist
Measure around your natural waist, usually the narrowest point between the bottom rib and the top of the hip.
How to measure your hips
Stand with your feet together and measure around the fullest part of your hips and seat.
Use your measurements
Enter your chest measurement in the clothing size calculator and then check the retailer’s own chart before ordering.
