Article: Wrap a soft tape measure under your arms and around the fullest part of your chest.  Stand in front of a mirror or ask for help from another person to make sure that the tape measure is parallel to the ground all the way around. Bring the tape measure together in the front to make it easier for you to read the numbers. Wrap a soft tape measure around the narrowest part of your torso.  The narrowest part of your torso is usually immediately above your belly button or somewhere in that area. Make sure that the tape measure is completely parallel to the ground all the way around. To double-check this, continue standing in front of the mirror or getting help from another person. Wrap the tape measure around your back and bring it together in the front. One piece should match your bust measurement and the other should match your waist measurement. Add roughly 4 inches (10 cm) of extra length so that you can tie the elastic together. Tie the elastic together to form bands and trim off most of the excess on the ends.  Slip the elastic over your bust and waist to make sure that it is fits. If it is too loose or too tight, re-tie it and try again. Knot the elastic to secure it in place.

What is a summary?
Measure your bust. Measure your waist. Cut two pieces of elastic based on these measurements. Tie and trim the elastic.
