This size chart is to determine your clothes size. If any of your measurement is on the borderline between two sizes, you can pick the smaller size for a tighter fit or the larger size for a looser fit. If your chest and waist measurements correspond to two different suggested sizes, you should order the one which is indicated by the measurement of your chest.
Tips To Measure:
Start with your bust : measure the fullest part of your bust, keep the tape parallel to the ground.
For your waist : measure around your waist at the narrowest part of your torso. Keep tape parallel to the ground and one finger between the tape and your body.
Your hip - Stand with your heels together and measure around the fullest part of your hip, keeping the tape parallel to the ground.
