How do you choose your size?
Here are some tips that can help: Measure yourself with a tape measure. If you do not have a measuring tape on hand you can measure with a wire and then measure its length with a ruler.
Chest circumference measurement:
Place the ribbon/wire on the widest circumference of the chest, making sure the measurement is not too tight
Waist circumference measurement:
Circle the ribbon around the narrowest part of the waist.
Hips circumference measurement:
Circle the ribbon around the narrowest fullest part of the thighs
