Geometric Diamond Cage Chest Harness in Black Faux Leather

This geometric diamond-cage chest harness is a strappy harness built from black faux leather, arranged in a triangular body cage pattern that meets at a single O-ring below the collarbone. Silver-tone rivets mark every strap intersection, holding the cage shape in place while a separate waist strap cinches with a metal buckle. Styled as a fashion harness rather than underwear, it sits over a top or dress and works as a layering piece for festival, rave, and everyday streetwear outfits.

Diamond Cage Construction

The chest section is built from narrow straps, roughly 1 cm wide, crossed into a repeating diamond lattice instead of a single flat panel, the same body cage construction seen on festival harness styles, scaled down to a compact chest piece. A waist strap runs below the cage and closes with an adjustable buckle, so the harness can be tightened or loosened at the waist independently of the chest fit. The O-ring at the top acts as the anchor point where every diagonal strap meets, keeping the diamond shape from twisting once it is buckled on.

• Chest straps roughly 1 cm wide, riveted at each crossing point
• Single silver-tone O-ring anchors the straps below the collarbone
• Adjustable waist buckle separate from the chest strap adjustment
• Fully adjustable strap length at both shoulder and waist points
• Open cage front leaves the layered top or dress visible underneath

Styling & Occasions

Worn over a plain tank top or slip dress, this strappy harness reads as a going-out accessory rather than underwear. Layer it over a fitted black bodysuit and jeans for a rave or festival outfit, or over a slouchy grey t-shirt dress for a streetwear look with the diamond cage visible at the chest. Because the straps sit on top of fabric rather than against skin, it also works over a fitted blazer or open shirt for an evening outfit built around the harness detail instead of hidden underneath it.

Sizing & Fit

This chest harness is offered in six labeled sizes: XS/S, S/M, L/XL, 2XL/3XL, 4XL/5XL, and 6XL/7XL, so the strap and buckle range is built to adjust across a wide chest and waist span rather than one fixed shape. The smallest label suits narrower frames, while the largest label is cut with longer straps for fuller busts and waists; buyers sizing between two labels should size up for extra buckle room at the waist strap.

• XS/S and S/M fit narrower chest and waist measurements
• L/XL sits in the middle of the adjustable range
• 2XL/3XL through 6XL/7XL extend the fit for fuller busts and waists
• Waist buckle adjusts independently from the shoulder straps

Material & Care

The straps and waist band are made from black faux leather with silver-tone metal hardware at the rivets, O-ring, and buckle, a vegan leather harness build with no animal hide in the straps. Wipe the straps clean with a damp cloth rather than machine washing, since water and heat can stiffen or crack faux leather over time. Store it flat rather than folded at the diamond points to keep the cage shape from creasing, and keep the hardware away from direct moisture to slow tarnishing on the silver-tone finish.
