What the Ternary Harness Set Offers
The Ternary Harness Set is a three-piece ensemble: a neck-to-back harness, a waist belt, and a mesh G-string. All pieces share a consistent design language of adjustable elastic straps and large O-ring hardware, making it a cohesive statement set rather than a mix of separate accessories.
The harness uses metal hook closures at the neck and back, so you can put it on without threading straps through rings. The belt cinches your waist with a triple O-ring detail, and the G-string side straps attach to O-rings, letting you wear them as high on the hip as you like.
Key Product Details
- Ternary Harness Set: Our Ternary harness takes our classic tri harness style to another level, with fully adjustable straps for a perfect fit and striking large O ring hardware detail. Fully adjustable straps mean you can tailor the fit to your body shape, which is essential for a harness that needs to stay secure without digging in.

Ternary Harness Set - Ternary Harness Set: Fastens with metal hook detail at the neck and back. Metal hooks are quicker to fasten than buckles or ties, and they provide a secure closure that won't slip during wear.
- Ternary Harness Set: Soft satin and fully adjustable elastic strapping keep you comfortable. Satin-lined elastic reduces friction against skin, making the set more comfortable for extended wear compared to raw elastic or leather.
- Ternary Harness Set: Styled here with our Entwine bra in matching mesh. The harness set is designed to layer over or under other lingerie, so you can pair it with a bra or wear it alone depending on coverage preference.
- Ternary Harness Set: Handmade to order, please allow up to seven days for dispatch. Because each set is made after you order, sizing and customization options are more flexible, but you'll need to plan ahead for delivery.
Sizing and Fit Considerations
The Ternary Harness Set is available in sizes XXS through XXL, plus a Custom option. This range covers a wide variety of body shapes, but the Custom size is worth considering if you fall between standard sizes or have specific proportion needs.
All straps are adjustable, so the harness, belt, and G-string can be fine-tuned after you put them on. The O-ring attachments on the G-string side straps let you raise or lower the hip position, which is useful if you want a higher cut or more coverage.
The catalog does not include a sizing chart or specific measurement guidelines, so if you order a Custom size, be prepared to provide your own measurements at checkout. For standard sizes, the adjustable straps give some leeway, but the belt and harness have fixed O-ring spacing that may fit differently depending on your torso length.
Ternary Harness Set vs. Other Harness Styles
- Ternary Harness Set: Three-piece set with harness, belt, and G-string. Fully adjustable elastic straps, metal hook closures, and large O-ring details. Suitable for full-body layering or standalone wear.
- Classic Tri Harness (no belt or G-string): A simpler harness-only design without the waist belt or matching underwear. Less coverage and fewer adjustment points, but also less bulk and easier to conceal under clothing.
- Underbust Harness (e.g., Spite Underbust): Sits below the bust, leaving the chest bare. Usually has fewer straps and a more minimal look. Better for pairing with a bralette or going strapless, but doesn't provide the same waist definition.
Material and Care Notes
The set uses soft satin and elastic strapping, with metal O-rings and hook closures. The G-string is mesh, which is lightweight and breathable but more delicate than the elastic straps.
No specific care instructions are provided in the catalog, but handmade elastic lingerie generally benefits from hand washing in cool water and air drying away from direct heat. Avoid machine washing or drying, as the O-rings and hooks can snag other items or damage the elastic.
