Why customers love it
Shaping you can adjust, in a piece you can actually wear all day
Key features
Built around one idea: a defined waistline you can adjust, in a garment that stays comfortable enough to keep on.
Hook-and-zip closure
A double closure system: hooks set your compression level, the zip locks it in and keeps the front line smooth.
4 steel ribs
Flexible steel boning holds the shape of the garment and encourages an upright, supported posture.
Underbust cut
The underbust design sits below the bust and above the hip so it layers cleanly with your own bras and bottoms.
Breathable everyday fabric
A stretch-blend body designed to stay comfortable through a normal day of wear under clothing.
Designed for real life
Sculpted under everything you wear
Whether you're running errands, at work, or out with friends — smooth, secure and discreet under your everyday outfits.
Adjustable compression
Three rows of hooks let you choose how firm the fit feels, and adjust as the garment settles in over time.
Sculpted silhouette
The contoured panelling smooths the midsection and gives a defined hourglass line while it's worn.
Comfortable fit
Flat seams, a soft lining and flexible boning keep it wearable rather than restrictive.
Designed for everyday wear
Slim enough to disappear under a dress, a blouse or a workout top — at the desk, on errands or out.
Nuvia shapewear shapes your silhouette while it is being worn. It is not a medical device and is not intended to change your body permanently, burn fat or cause weight loss.
Fit & size guide
Measure the narrowest part of your natural waist, keeping the tape level and snug. If you fall between two sizes, choose the larger one and use the hook rows to tighten.

| M | 28–30 in / 71–76 cm |

What customers are saying
“The hook rows make all the difference — I started on the loosest one and moved in after a week. It smooths everything under a bodycon dress without a single line showing.”
“I've tried cheaper cinchers that roll down by lunchtime. This one stays exactly where I put it and the boning keeps me sitting up straight at my desk.”
“Beautiful shape and the zip feels sturdy. Sizing up was the right call for me — give yourself a few days to get used to the firmer rows.”
“Finally something supportive that doesn't dig in. I wear it under work clothes and honestly forget it's on.”
“The waistline it gives me under a fitted top is exactly what I wanted. Fabric feels premium, not plasticky.”
“Great everyday compression and the underbust cut works with my own bras. Took one star off only because I wish it came in more colours.”
Reviews reflect individual experiences with the fit and feel of the garment while worn.
Questions, answered
Measure around the narrowest part of your natural waist and match it to the size chart above. If you're between two sizes, size up — the hook rows let you tighten the fit as you go.
