How to Take Your Measurement
Use a flexible cloth or hemline tape measure to take your measurement accurately. If you do not have one, you can use a string as a measuring tool and then align with a ruler to retrieve the exact measurements. Measurements of actual garments may vary from style to style depending on the features and technology used.
Bust
With arms relaxed down at your sides, measure the fullest part of bust/chest, keeping tape parallel to floor.
Tip: With the tape in position, take a breath in and out, allowing it to slide to its most comfortable, non-binding fit.
Waist
Wrap the tape around your natural waist line. Measure around your natural waistline, which is the smallest area of the waist. This is normally found between the ribs and hips.
Tip: Remember to keep the tape measure slightly relaxed for a more comfortable fit.
Hips
Stand with your feet together, keeping the tape straight and parallel to the floor. Measure around the fullest part of the hips, where the top of your hip bones are located.
Torso
Start at your shoulder closest to your neck and take the tape down the front of your body and pass it under your crotch. Move it all the way up your back to meet the other end of the tape at your shoulder, it should look like a loop.
