Take your measurements  

 1- To measure your chest : 

The measurement is taken over a thin, unpadded bra, passing through the tip of the breasts, which is supposed to be the fullest part of the chest.

2- To measure your waist :

At the hollow of the waist and not necessarily at the level of the navel

 3- To measure your small hips: 

Around the “little hips” go through the two protruding bones of the pelvis that can be felt at the front of the body. If you can't use the bones as a guide, know that the small hips are usually halfway between the waist and the pelvis (the hips), a few inches below the navel.

4- To measure your hips : 
To measure your hip circumference, you must put on your underwear. Stand up straight with your feet hip-width apart. Place the tape measure around the widest part of your hips (usually your buttocks). As a general rule, the hip circumference is 15-20 cm below your waist. Don't pull too hard on the tape measure. Write down the corresponding measurement.
