The first bra designed from the ground up for women who went flat after single mastectomy. Built-in asymmetric padding. A 7-layer system that stays put. Zero prosthetics. Zero inserts. Zero second bra.
A technical flat from our design specification. Left side: single cup with lace trim edging. Right side: wide flat band, no cup, Y-strap construction (diagonal cross strap + straight strap merge at Y-join connector). Asymmetric underband: 22–24" breast side, 20–21" flat side. Seam allowances: ¼" (6mm) throughout. Hook & eye back closure. Nothing else on the market does this.
Technical flat — front + back views. Left side: single cup with lace trim. Right side: wide flat band + Y-strap (Y-join connector at shoulder). Underband: 22–24" breast side · 20–21" flat side. Seam allowance: ¼" (6mm). Hook & eye back closure.
No single feature solves migration alone. All seven work in concert. Any three of the seven should hold the bra in position independently — the full system is deliberately over-engineered.
Medical-grade silicone dot grid on the flat-side band, cup edge, and lateral panel. 2–4× higher friction than fabric-to-skin. Dot pattern maintains airflow.
Breast-side underband is engineered to 22–24" circumference; flat-side underband runs 20–21" — narrower because there's no breast weight to distribute. The width differential is engineered into the band itself, not just the cut. Higher power mesh GSM on the flat side compensates for the missing breast weight anchoring.
Three 4mm spiral steel bones on the flat side only. One vertical (prevents roll-up), one angled at 12° (blocks center drift), one at the gore junction. All housed in cotton-jersey channels — zero metal-on-skin.
Heat-molded 3-piece cup conforms to the post-mastectomy chest wall. Eliminates the air gap that allows flat panels to slide. Full-surface contact means full-surface friction.
Internal elastic tether connects the flat-side cup to the 30mm center gore. Creates a mechanical stop against center drift. Even if the cup starts to migrate, the tether physically prevents it.
On the flat side, a diagonal cross strap and a straight strap merge at a Y-join connector at the shoulder. This geometry routes tension from two angles simultaneously — inward and downward — holding the flat panel in place without a cup to anchor it. Dual adjuster at the Y-join allows precision tuning independently of the breast-side strap.
Removable micro glass bead insert (40–100g by cup size) simulates partial breast weight. Creates downward tension that reduces ride-up. Ships included; fully removable for washing.
This editorial illustration captures The Balance's design philosophy: the Y-strap construction, the asymmetric underband, the structured 3D foam on the flat side — every detail is a deliberate statement. Not a correction. A declaration.
Zero sewn seams on the interior flat side. All edges bonded or heat-sealed. Medical-grade silicone (same as scar therapy sheets). No labels sewn into the cup — heat transfer only. OEKO-TEX certified materials throughout.
Stretch lace overlay on the breast-side cup. Matte gold hardware on rings, sliders, and hooks. Lenzing MicroModal fabric (pH-neutral, ultra-soft, OEKO-TEX certified). This is lingerie — it happens to solve a functional problem.
A standard mastectomy bra + silicone prosthetic runs $140–$430. The Balance is $68–78 and replaces both. No accessory shopping. No monthly prosthetic maintenance. One product.
Designed by a single-mastectomy survivor who literally wore this bra DIY for years before productizing it. Every detail in this spec comes from lived experience — not from a focus group or a medical device team.
Designed to pass the 8-hour test with under 5mm of cup migration during normal activity. Exercise configuration via included racerback clip. Optional weighted balance insert for gravity equalization.
Available S/M/L/XL — sized to your natural breast side, with Left or Right mastectomy side designation. The breast-side underband is engineered to 22–24" and the flat-side underband to 20–21", calibrated independently so both sit true without adjustment.
Every material was selected against two criteria: Does it work technically? Does it feel luxurious? Nothing made the cut that failed either test.
94% MicroModal / 6% Spandex. 140 GSM jersey. pH-neutral, hypoallergenic, OEKO-TEX certified. Absorbs 50% more moisture than cotton. The cup fabric — both sides.
Two different GSM weights: 160 GSM (breast side) and 200 GSM (flat side). The tension differential is engineered into the fabric itself — not just how it's cut.
Platinum-cured, Shore A 20–30. Same grade as scar therapy sheets (ScarAway, Mepiform). Applied as 3mm dot grid for airflow. Zero irritation on surgical scars.
4mm spiral steel, plastic-tipped. Three on the flat side only. Maintains shape through 500+ flex cycles. Housed in double-lined cotton-jersey channels — never contacts skin.
The full design brief — where the color story came from, how the Lenzing MicroModal was chosen, and what editorial references shaped the product's visual identity.
I spent years improvising — stuffing prosthetics under bras, layering sports bras on top just to hold everything in place. The solution I needed didn't exist. So I built it. Not as a medical device. As the bra I actually wanted to wear.
