Hello, customer?
Thank you for your order:)
The model is size 55.
Free size means one size.
So it means 55 to the normal size, and the right size for the right body type.
There is a section size chart below.
I marked it in cm.
I recommend you to check and place your order.
And if it's size 55, if the breast cross section is over 50 centimeters,
It is often very large in size.
Check this part and order it.
