Overbust measurements in inches

The ‘Brenna’ harness can be worn with lingerie on its own or even casually over a day to day outfit. For extra opulence pair it with one of my chain belts.

The chain material is aluminium. I will need underbust measurements for this piece. It is available in a thinner chain and thicker chain - check the product images there is an example of both. And in gold or silver.
