Juliette bra size guide
STEP 1: MEASURE YOUR BACK CIRCUMFERENCE. To measure your back circumference, you must pass the tape measure just below your chest, without a bra and without tightening.
Ex: If you measured 76 cm for your back circumference, you are therefore between 75 and 79 cm , or a size 90.
STEP 2: MEASURE YOUR CHEST SIZE. To measure your chest size, you must pass the tape measure over your chest at nipple level without wearing a bra and without tightening it.
Ex: If you previously defined a size 90 for your back measurement, and you measured 88 cm for your chest measurement, you are therefore between 87 and 89 cm, or a B cup. Your size is therefore 90B.
STEP 3: FIND YOUR SIZE. Juliette bra sizes range from 32 to 46.
Ex : For a 90B, you should take a 38.
Reminder of the equivalences for the smallest sizes:
