Cross-Back Chest Harness with Adjustable Underbust Band

This black faux leather chest harness is built around a structured wide underbust band that sits firmly below the bust, paired with two diagonal back straps that cross at the center spine to create a clean X configuration. Unlike single-strap or cage-style designs, the cross-back geometry distributes tension evenly so the harness stays positioned without constant readjustment during wear.

Strappy Harness Styling and Occasions

Wear it over a sheer black turtleneck for a festival look, or layer it directly over skin beneath a blazer for a evening-adjacent edge at a night-out. The minimal silhouette pairs with high-waisted leather trousers without adding visual bulk at the waist, and the clean X-back reads well under sheer or open-back tops where cage hardware would overwhelm.

• Festival layering over mesh tops or bodysuits
• Evening aesthetic shoot styling — harness only or with high-waist briefs
• Night-out accent over a fitted blazer with the lapels open
• Open-back dress or top with the X-back fully visible

Sizing and Fit Details

The underbust band adjusts via two side buckles, each with multiple punched holes spanning approximately 60 cm to 100 cm around the ribcage. The shoulder and chest straps carry additional adjustment points that allow roughly 25 cm of range per strap, making the harness wearable from an XS frame to a plus-size 7XL torso. Note: the straps measure approximately 1.5 cm wide — buyers who prefer wider coverage over the chest may find them minimalist compared to a cage or waspie style.

• Underbust band: adjustable 60 cm to 100 cm circumference
• Strap width: approximately 1.5 cm throughout
• Sizes covered: XS through 7XL with multi-point adjustment
• Not recommended as a structural bra substitute — fashion accessory only

Faux Leather Material and Care

The straps and band are constructed from smooth-finish vegan faux leather — a PU-coated fabric that mimics the look of polished leather without using any animal-derived materials. Silver-tone metal D-rings, buckles, and dome rivets are used throughout; the hardware has a brushed finish that resists fingerprints better than high-polish chrome. To clean, wipe with a damp cloth and mild soap; avoid submerging in water or machine washing, as prolonged moisture weakens the PU bond at the strap edges. Store flat or hanging to prevent permanent crease marks.

• Outer: smooth PU faux leather, animal-free and vegan-friendly
• Hardware: silver-tone zinc-alloy buckles and D-rings
• Rivets: dome-head, press-set, flush with strap surface
• Care: wipe clean only — no machine wash, no soaking

Harness Bra Wearability Notes

Because the underbust band is the structural anchor, wearing it over a bralette or bandeau adds comfort during extended wear — the band alone does not provide breast support. The cross-back strap angle means most standard bra straps will show; a strapless bra or no bra works best if you prefer the harness straps as the sole visible element. The total weight of the piece is light enough that it does not pull down collarbones during a full evening of wear.
