Most bras just hold you up. This one also reminds you to keep your shoulders back, keeps underwire out of the picture and smooths your back under tops. Here's what each part does for you.
- Body fabric: 65% Polyamide / 35% Elastane — breathable, four-way stretch
- Insert fabric: 56% Polyamide / 44% Elastane — extra stretch for shaping support
- Fit: Wide band that fastens at the front — you choose how snug it feels while you can see it
- Support: Light lift from a soft, wide band — no underwire, nothing pinching
- Cups: Smooth, no seams — full coverage that doesn't show under fitted clothes
- Straps: Cross at the back — the weight sits on both shoulders, so they don't dig in
- Back: Wide and seamless — helps smooth bra-line bulges under shirts
- Inner lining: Soft-touch microfiber against the skin
- Sizes: S · M · L · XL · 2XL · 3XL
- Designed for: All-day wear — desk, errands, travel, lounging
Care: Wash with like colors. Do not bleach. Do not tumble dry. Hang dry. Do not iron.
It stretches, so each size fits several regular bra sizes. Available in S through 3XL. Two simple ways to find yours below.

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, with relaxed posture and a non-padded bra on (or no bra).
- Your size: your underbust decides. If your bust fits two sizes, go with your underbust. Tolerance ±1 cm (0.4").

Will it really help my posture?
It's a gentle reminder, not a brace. The straps cross at the back and you feel them when you start to slouch, but the bra won't hold you upright on its own. It isn't 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's made for all-day comfort, not for running or high-impact workouts, and not for holding a very full bust firmly.
Is it actually comfortable for full-day wear?
Yes. No underwire, a soft lining against your skin, and straps that cross at the back so the weight is spread across both shoulders.
Does it work for larger busts?
The range goes up to a 42DD. It gives light support, so if you're a DD or fuller and need a firm hold, it may not be enough for you. Measure your underbust and use the size guide to pick your size. For very high-impact activities (running, cardio), a dedicated sports bra is still the better choice.
How do I find my size?
Measure your underbust: it decides your size. Tap Find My Size above for the full chart in cm and inches. If your bust fits two sizes, go with your underbust.
Will it show under my clothes?
The cups have no seams and the back is wide, so it's designed to sit smoothly under fitted shirts, dresses and knitwear.
How do I put it on?
Three simple 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's on, you can move to a tighter row. The first time can take a minute, so give yourself a try or two. If anything isn't clear, email us and we'll walk you through it.
Made for real days.
See how the straps remind your shoulders to stay back, with no stiff brace and no underwire.

Customers praised this wireless front-closure bra for its posture support and comfort. Many said it "helps with posture" and reduces back pain. The material quality is excellent. However, fit varies - works "great for smaller sized women" but some full-breasted customers found fitting challenging. Support level received mixed feedback.

It took me a minute to figure it out, but it definitely helps with my posture, which ultimately helps with my back pain.
