Cage Bra Harness in Black with Adjustable Elastic Straps

This black cage bra harness combines a set of stretch elastic straps into a triangular cage shape, connected at four points by silver-tone O-rings and a central triangle ring beneath the collarbone. Built as a standalone strappy harness, it sits either over a top or directly on skin, working as a chest harness rather than a full bra with cups. Adjustable buckles at the shoulders and underbust let you set the cage tighter or looser depending on how you plan to wear it.

Strap & Hardware Design

The frame is made from black stretch elastic straps roughly 1.2 cm wide, routed through silver-tone metal O-rings at the shoulders, sternum, and underbust. A single triangle ring sits at the front connection point, giving the harness its cage-like structure instead of a solid front panel. Because the straps are elastic rather than rigid faux leather, the harness moves with the body and layers flat under a jacket or over a fitted top.

• Silver-tone O-rings at four strap intersections
• Central triangle ring anchoring the front cage shape
• Adjustable buckles on both shoulder straps and the underbust band
• Straps measure approximately 1.2 cm wide for a fine, linear silhouette
• Open-front cage design with no bra cup or lining piece

Festival & Streetwear Styling

Worn as a rave outfit harness, this piece layers over a plain black bodysuit or bralette for a festival look, with the O-rings catching light against a solid base color. For a streetwear combination, wear it directly over a fitted black crop top with high-waisted denim, letting the straps sit visibly across the chest. It also works over an open blazer for an evening-out outfit, since the elastic straps stay flat against fabric instead of sliding off the shoulder.

Sizing & Fit

This chest harness is offered across six size bands, from XS/S up to 6XL/7XL: XS/S, S/M, L/XL, 2XL/3XL, 4XL/5XL, and 6XL/7XL. Each band's elastic straps stretch to cover a range of shoulder and underbust measurements, though the O-ring spacing is fixed, so the cage sits slightly higher on a narrower frame and slightly lower on a fuller one. Buyers between two bands should size up, since the elastic has more give when let out than when it is already at full stretch.

• XS/S and S/M fit narrower shoulders and a smaller underbust measurement
• L/XL and 2XL/3XL suit a mid-range frame with stretch left in reserve
• 4XL/5XL and 6XL/7XL extend both strap length and underbust band for a fuller fit
• Sizing runs by band, not by a single number, so check both halves of the label

Material & Care

The straps are cut from matte black stretch elastic paired with silver-tone metal hardware; there is no fabric lining, so the elastic rests directly against skin or a base layer. Hand wash the straps in cold water with a mild detergent, then lay them flat to dry away from direct heat. One trade-off worth noting: repeated machine washing or high heat can loosen the elastic's tension over time, so hand washing keeps the cage shape holding its structure longer.
