Adjustable Strappy Underbust Harness & Thong Set

This two-piece black strappy underbust harness and thong set pairs thin elastic straps in a geometric cage pattern with gold-tone O-ring connectors at the chest and neck points, creating a defined silhouette without bulk. The underbust harness sits below the bust line, leaving the torso open while the matching thong keeps the look cohesive from top to bottom.

Strap Configuration & Hardware Detail

The harness upper features a dual-strap neck connection with two O-rings that anchor a V-shaped chest frame, running down into a horizontal underbust band. A single central strap bridges the chest panel, adding structure. The matching thong mirrors the strap aesthetic with side strapping. All hardware is gold-tone metal, contrasting sharply against the black elastic.

• Gold-tone O-ring connectors at neck and chest anchor points
• Thin elastic straps approximately 0.6 cm wide throughout
• Geometric V-frame chest panel with central bridge strap
• Matching thong with mirrored strap detailing at hips
• Fully adjustable slider closures on shoulder and underbust bands

Evening & Festival Styling

Wear the harness set as intimate fashion on its own for a evening shoot or private occasion, or layer the harness top over a sheer bodysuit and high-waisted trousers for a festival-ready strappy harness look. The underbust framing works particularly well under an open blazer — the O-rings sit visible above the lapels for a fashion-forward edge. Pair with thigh-high stockings, as seen in the product image, to extend the vertical line.

• Layer over a sheer white blouse for a festival body harness outfit
• Wear alone as intimate lingerie for evening aesthetic styling
• Style under an open blazer with the O-rings showing at the neckline

Sizing & Fit Guide

The adjustable elastic construction fits a bust range of approximately 70-130 cm (XS through 7XL) and an underbust range of 60-120 cm. The neck straps extend to accommodate longer torsos. The thong uses standard size-graded elastic waistbanding. Note: because the straps are narrow elastic rather than rigid faux leather, the harness offers light compression only — it will not provide the structured lift of a wired bra. Buyers seeking firm underbust support should size down one step for a snugger fit.

Material & Care

Straps are constructed from nylon elastic with a matte black finish; the O-ring hardware is zinc alloy with gold-tone plating. The thong gusset uses a soft cotton-blend lining for comfort against the skin. Hand wash in cold water with a gentle detergent — machine washing will degrade the elastic over time. Do not tumble dry or iron. Pat dry with a towel and air-flat to preserve strap elasticity and hardware plating. With proper care the elastic retains its tension for approximately 30+ washes before noticeable stretch occurs.
