Strappy Cage Bralette Harness Adjustable

The strappy cage bralette harness is a black elastic harness bra built from thin straps that cross into a triangle cage across the chest. Instead of cups, a series of 0.6 to 1 cm wide elastic bands forms the geometric shape, so it works as a standalone chest harness or as a layering piece over a plain top. Six size labels, from XS/S to 6XL/7XL, cover many underbust measurements.

Cage strap configuration

The front of the harness is built from a single continuous elastic band that crosses at the center to form a downward-pointing triangle, with a horizontal bar bridging the two sides at mid-chest. There is no padding or boning inside the straps, so the cage keeps its shape through tension rather than structure. The back straps run over the shoulder and down to a horizontal band under the bust, and every strap on this strappy harness measures close to 1 cm across.

• Single continuous strap forming the front triangle cage
• Horizontal bar bridges the straps at mid-chest
• Underbust band closes the shape at the bottom
• No boning, wiring or padding inside any strap

Cage bralette styling

This chest harness works best layered rather than worn alone in most settings. Over a fitted black t-shirt, the cage sits on top and the geometric lines show through as a going-out layer for a festival or a night out. Over a plain triangle bralette in a matching or contrasting color, the straps read as a harness bra, which suits a boudoir photo set or an evening look under a sheer or open blazer. Because the straps sit flat, it also layers under an open shirt for a subtler daytime version of the same silhouette.

• Fitted black t-shirt with the cage layered on top for festival looks
• Plain triangle bralette underneath for a boudoir-ready harness bra look
• Open shirt or blazer worn loose over the straps for daytime layering

Size range and fit

This strappy cage bralette harness is sold in six size labels only: XS/S, S/M, L/XL, 2XL/3XL, 4XL/5XL and 6XL/7XL. Because the straps stretch, each label covers a range rather than one exact measurement, and the shoulder straps have sliders that add a few extra centimeters of adjustment on each side. The design sits close to the body, so it is not intended to fit loosely or to be layered over thick winter fabrics.

• XS/S and S/M fit a smaller frame and narrower shoulder width
• L/XL and 2XL/3XL fit a mid-range bust and underbust measurement
• 4XL/5XL and 6XL/7XL fit a fuller bust and broader shoulder line
• Shoulder sliders add roughly 5 cm of adjustment on each side

Elastic strap material

Every strap on this harness bra is cut from a stretch nylon-spandex elastic, which gives the cage its shape without any rigid support. The straps have no lining, since they are designed to sit directly against the skin or over a plain bra, and they carry no metal hardware. Hand wash the straps in cool water and lay them flat to dry, because tumble drying can weaken the elastic recovery over repeated washes. With normal wear the straps hold their shape for regular rotation, but stretch elastic in this style typically loosens gradually over a year or more of frequent use, which is an honest trade-off with any bonded elastic band.

• Stretch nylon-spandex elastic straps, about 1 cm wide
• No lining, boning or metal hardware anywhere on the straps
• Hand wash in cool water and lay flat to dry
• Elastic recovery gradually loosens with a year or more of frequent wear
