A harness bra that leaves nothing to be desired:
This bust-free sturdy split leather (2.1 - 2.3 mm thick) bra is studded with decorative metal rivets. The size of the cups can be individually adjusted with buckles, and the neck strap is adjustable in front with two buckles. In the back the bra also has a buckle closure.
The shown briefs and the cuffs are not included.
