How It Works

Most bras only hold you up. This one also reminds you to keep your shoulders back, leaves underwire out of the picture and smooths your back under tops. Here is what each part does.

A reminder to stand tallThe straps cross at the back. When you start to slump over a desk, a phone or a long day, you feel them — your cue to roll your shoulders back. A quiet reminder built into a bra you wear anyway.

No underwire, nothing digging inA soft, wide band under the bust gives a light lift, so there is no wire pressing or pinching by the end of the day.

A smoother back under topsThe wide, seamless back helps smooth the bulges most bras push up, for a cleaner line under fitted shirts, dresses and knitwear.

First wearLight lift, a gentle pull-back on the shoulders, a smoother line under tops

Size & Fit

It stretches, so each size covers several regular bra sizes, from S to 3XL. Two easy ways to find yours:

Between two sizes? The smaller one fits closer; the larger gives more room. With a fuller bust, choose the larger one.

Option 1 — By body measurements (recommended)

Size	Underbust	Bust	US / UK	Weight
S	28–29.9"71–76 cm	31.1–34.6"79–88 cm	32A–32B	99–121 lb45–55 kg

How to measure

Underbust (band): wrap a soft tape directly under your bust, where the band sits. Keep it level and snug, not tight.
Bust: around the fullest part of your chest, standing relaxed, wearing a non-padded bra or no bra.
Your size: the underbust decides. If your bust falls into two sizes, go by your underbust. Tolerance ±1 cm (0.4").

Weight is only a guide — your underbust is the most precise measure. Still unsure? Email us your measurements and we will choose for you.

FAQ

Will it really help my posture?

It is a gentle reminder, not a brace. The crossed straps let you feel when you start to slouch, but the bra will not hold you upright on its own. It is not a medical device — if you have a back or shoulder condition, check with your doctor first.

How much support does it give?

Light, everyday support from a wide wireless band. It is made for all-day comfort, not for running or high-impact workouts, and not for holding a very full bust firmly.

Is it comfortable for a full day?

Yes. No underwire, a soft lining against your skin, and straps that cross at the back so the weight is shared across both shoulders.

Does it work for a larger bust?

The range goes up to 42DD. Because the support is light, if you are DD or fuller and need a firm hold, it may not be enough. Measure your underbust and use the size guide. For high-impact activity such as running, a dedicated sports bra is still the better choice.

How do I find my size?

Measure your underbust — it decides your size. The Size & Fit section above has the full chart in centimetres and inches. If your bust falls into two sizes, go by your underbust.

Will it show under my clothes?

The cups have no seams and the back is wide, so it is designed to lie smoothly under fitted shirts, dresses and knitwear.

How do I put it on?

Three easy steps: 1) pull it on over your head like a tank top; 2) reach behind you, take the wide band and bring it round to the front; 3) hook it at the front, starting on the loosest row — once it is on, you can move to a tighter one. The first time may take a minute. If anything is unclear, email us and we will guide you.
