SculptKey combines a seamless T-shirt finish with flexible bonded jelly support and a separation-focused keyhole centre. Fuller-coverage ¾ cups, fixed thin padding, adjustable straps and a four-row back fastening provide comfortable Medium Support without traditional underwire.
Meet SculptKey, the seamless wireless bra designed to combine everyday comfort with medium support and a distinctive keyhole centre. Its smooth finish disappears more easily beneath T-shirts and fitted layers, while the sheer mesh insert adds a considered detail that also helps visually separate the cups.
Flexible bonded jelly strips follow the underbust and sides, creating a supportive frame without traditional wire. This construction gently lifts and steadies the bust while allowing the bra to move with you. The separation-focused centre is designed to reduce the compressed “uniboob” effect sometimes created by pull-on bralettes, although final shaping will depend on your breast shape and chosen size.
Fuller-coverage three-quarter moulded cups contain the bust through daily movement. Thin fixed pads provide smooth coverage without removable inserts shifting inside the cup. Graduated adjustable straps distribute support across the shoulders, with wider construction used in larger sizes. A classic three-hook, four-row back fastening lets you fine-tune the band as it naturally relaxes with wear.
Seamless fabric creates a soft, second-skin feel across the back and underarms. The high-stretch blend contains 64.8% nylon and 35.2% spandex, balancing flexibility with recovery. It is intended to smooth the bra line and accommodate everyday movement, not to replace specialist sports support or a medically fitted bra.
SculptKey provides Medium Support. It offers more structure than a light bralette, while remaining wireless and flexible. Wear Black beneath dark tailoring and evening layers, or choose Honey Beige as a neutral foundation under pale shirts, knitwear and dresses. The clean cup surface makes both colours work well under close-fitting tops.
Available in sizes S through 3XL, SculptKey uses a combined band-and-cup chart rather than standard body measurements. Measure your underbust and fullest bust, identify your usual band and cup, then follow the official conversion table. Do not size down to create extra lift. If you sit between options, prioritise a secure band that remains level and cups that contain without spilling or gaping.
The reference model measures 37.4 inches at the bust, 26.38 inches at the waist and 44.49 inches at the hips and wears size M. These measurements show the garment on one body and do not define the full size-M range. Hand wash cold, do not machine wash, wring or iron, and air dry away from direct heat to protect the bonded support and fixed padding. It is a polished everyday option for customers seeking wireless support with separation.
Separation-Focused Keyhole Centre: The centre opening and sheer mesh detail help define the space between the cups, reducing the compressed appearance associated with some seamless bralettes.
Flexible Bonded Jelly Support: Bonded jelly strips create a supportive frame beneath and around the bust without using rigid traditional underwire.
Official Medium Support: SculptKey provides more structure than a light-support lounge bra while retaining the flexibility of a wireless design.
Fuller-Coverage ¾ Cups: Three-quarter moulded cups provide greater containment through the upper and outer bust than a demi-cup or low-plunge bra.
Fixed Thin Padding: Integrated, non-removable pads create smoother coverage without loose inserts folding or moving inside the cups.
Adjustable Graduated Straps: Adjustable shoulder straps help balance the cup position. The supplier uses wider construction in larger sizes, reaching approximately two centimetres.
Three-Hook Back Fastening: Three hooks provide a broader anchor across the back than a narrow two-hook closure.
Four Rows of Adjustment: Four fastening positions let customers fine-tune the band and move inward as the fabric naturally relaxes with wear.
Seamless T-Shirt Finish: Smooth construction helps reduce prominent seams beneath fitted tops, dresses and knitwear.
Underarm and Back Smoothing: Wide seamless side and back panels follow the body and help create cleaner lines beneath clothing.
Two Foundation Colours: Black works beneath dark outfits, while Honey Beige provides a neutral option for lighter clothing.
64.8% nylon, 35.2% spandex
The high-elastane seamless fabric provides flexibility and shape recovery while supporting a close, smooth fit across the cups, sides and back.
Gently hand wash in cold water with mild detergent.
Do not machine wash, wring or iron. Avoid bleach, tumble drying and direct heat. Reshape carefully after washing and lay flat to air dry.

The SculptKey Edit · Wireless Bra Buying Guide
SculptKey combines flexible bonded jelly support with a separation-focused keyhole centre, fuller-coverage ¾ cups, fixed thin pads, adjustable straps and a three-hook, four-row back closure. It creates a smooth Medium Support foundation without conventional underwire.
How to Style SculptKey
SculptKey is designed primarily as an underlayer. Match the bra colour to the outer fabric, settle the fixed pads and adjust the band and both straps before building the finished look.
Wear Honey Beige beneath an ivory or pale-blue blouse with tailored trousers and a blazer. The seamless cups keep the foundation quiet beneath polished professional layers.
Best for · Work / meetings / polished errandsPair Honey Beige with a fitted T-shirt, straight denim and clean trainers. Begin on the loosest secure hook row so the band can be adjusted as it naturally relaxes over time.
Best for · Brunch / travel / daytime plansChoose Black beneath a dark wrap top or fitted knit. The keyhole centre encourages a more defined cup line while the smooth outer surface keeps the bra discreet beneath the outfit.
Best for · Dinner / date / fitted layersLayer Black beneath a structured evening top or dark dress. Let the outer neckline conceal the straps and centre mesh, then finish with one controlled metallic or red accent.
Best for · Cocktails / events / night-out plansBefore You Buy
This is a seamless wireless bra with bonded jelly support and fuller ¾ cups. The centre is designed to encourage visual separation, but the finished shape still depends on anatomy and fit.
Fit Check
Select SculptKey from your usual US/UK band and cup combination—not dress size or full-bust measurement alone. Do not size down to create additional lift.
The fixed pads should lie smoothly, the ¾ cups should contain without overflow and the bonded support should follow the lower bust. The centre should sit comfortably, while the band remains level and the adjustable straps support without carrying the full weight of the bust.
Try SculptKey carefully while all product tags remain attached and assess it beneath the intended outfit.
Official Conversion
The supplier supplies a band-and-cup conversion—not body-measurement ranges. Each letter size covers only the combinations shown below.
The reference model measures 37.4″ at the bust, 26.38″ at the waist and 44.49″ at the hips and wears M. Those measurements show the garment on one body; they do not define the full M fit range.
Quick Answers
Clear answers about SculptKey support, jelly construction, keyhole shaping, fixed pads, fuller-bust fit, colours, fabric and care.
The supplier classifies SculptKey as Medium Support. It provides more structure than a light bralette while retaining the flexibility and movement of a wireless everyday bra.
Yes. Flexible bonded jelly strips support the lower cups and sides without conventional metal underwire. The bra is structured, but no traditional cup wire is listed.
The centre opening and sheer mesh detail are designed to define the space between the cups and reduce the compressed appearance created by some pull-on bralettes. Results depend on anatomy and fit.
No. The thin pads are fixed inside the moulded ¾ cups. This helps prevent loose inserts from shifting, folding or requiring repositioning after every wear.
The fuller ¾ cups, bonded side support, graduated straps and three-hook closure are designed with greater containment in mind. Suitability depends on the exact chart combination and fit.
Use your usual US/UK band and cup combination and select the corresponding S–3XL size shown above. Do not choose by dress size or size down in an attempt to create stronger lift.
SculptKey comes in Black and Honey Beige and is made from 64.8% nylon and 35.2% spandex. Screen settings, studio lighting and natural light can slightly alter colour appearance.
The official care instructions specify cold hand washing, no machine washing, no wringing and no ironing. Fasten the hooks, reshape gently and air dry away from direct heat.
