Grab you tape measure and use the following indications to help :
- Bust measurement : measure at the largest point
- Waist measurement : at the narrowest point
- Hip measurement : at the widest point of your bottom
Don't pull the measuring tape too tightly and don't suck your stomach in, it's not a competition :)
Always choose the larger size if one of the measurements corresponds to the size indicated.
Example : 89 for the bust & 73 for the waist = size 40
