Le Soutien-gorge Posture — Maintien sans armatures, dos croisé
It pulls your shoulders back, not your bra straps down. A wireless bra with straps that cross in an X across the back — so the weight is carried across your back instead of hanging off two thin straps.

What it actually does
Six things are doing the work here, and the one that matters most is out of sight — the straps cross in an X across your back. Tap the diagram to see it full size.
Why this one
- Front closure. A column of hook-and-eye fastenings down the centre front — you can see it and reach it, instead of fighting a clasp behind your back.
- Cross-back. The straps cross across the shoulder blades. That panel is the posture correction, and it is why the straps never dig.
- Wide vest straps, about three fingers wide, so the weight is spread rather than cutting a line into the shoulder.
- Wire-free with soft moulded cups. Nothing to dig in under the bust.
- Wide smooth underband that spreads pressure across the ribcage instead of gripping in one place.
- Cotton and nylon blend — it lets heat and moisture out instead of trapping it.
Colours
Black, beige and white — the three the factory actually makes.
Size guide — read this before you order
This is our widest size run: S all the way to 5XL. One cup size that stretches to fit — the band is what you are choosing, so go by your under-bust measurement rather than your cup letter.
| Size | Under-bust |
|---|---|
| S | 28–30" |
| M | 30–32" |
| L | 32–34" |
| XL | 34–36" |
| XXL | 36–38" |
| 3XL | 38–40" |
| 4XL | 40–43" |
| 5XL | 43–46" |
This one runs small. Take one size up from the band you normally buy. If you are between two, take the larger — the back panel needs to sit flat across the shoulder blades to do its job.
Email your under-bust measurement to support@luma-nyc.com and we will tell you which to take. Full size guide.
Questions
Is this a medical posture brace? No. It's a bra with a crossed back panel. It encourages you to hold your shoulders open — it does not treat any condition, and we don't claim it does.
How does it fasten? A column of hook-and-eye fastenings down the centre front.
Will it flatten me? No. The cup gathers and lifts rather than compressing.
Can I wear it under a t-shirt? Yes — it's seamless and the back panel sits flat.
Between two sizes? Size up, every time.
