1. Chest : Measure around the fullest part of your bust, keeping the tape measure level and snug but not tight, with your arms relaxed at your sides and the bra you normally wear underneath.

2. Waist : Measure around the narrowest part of your waist, just above your belly button, keeping the tape measure level. This is where the shaping band sits.

  • 📏 Tips :
    Stick to your usual size. If you're between sizes, we recommend sizing up for optimal comfort. Go by your chest measurement: it's the one that decides whether the shirt sits right across the bust and shoulders.

  • 🧵 Fabric Info :
    Our 3D T-shirt is knitted with a crossed shaping band that holds the stomach and the sides, and a back panel that straightens your posture. The stretchy, sculpting fabric adapts naturally to your body shape, never too tight. Just enough for comfortable support.

  • 🔁 Easy Exchange :
    Si the size isn't right once you receive your order, no worries: simply send the item back and we'll ship you the correct size.

Before & After from our customers ⭐

Before & After Emma (38 years old)

I recognize myself again

After two pregnancies, I cried when someone asked if I was pregnant. This T-shirt smooths my stomach the moment I put it on. After six weeks, my skin feels firmer, my waist looks more defined, and I am wearing fitted dresses again.

Bafore & After Claire (43 years old)

The belly menopause left behind

At menopause, weight settled on my belly almost overnight. Shapewear pinched and rode up. This T-shirt instantly smooths my tummy, defines my waist and helps me stand taller. I have worn it under my sweaters for eight months, and my figure has genuinely changed.

Before & After Hannah (31 years old)

The lower belly the gym could not shift

I work out three times a week and eat well, but my lower belly would not go away. From day one, this T-shirt shaped my figure under clothes. After three weeks, my waist looked more defined, my jeans buttoned easily, and it felt comfortable all day.

Before & After Charlotte (36 years old)

Before & After Sophie (41 years old)

You know the top you keep reaching past. The one that sits fine until you sit down.

The 3D Sculpting T-Shirt is built to hold. The shaping lines are knitted straight into the fabric, not printed on it: a wide crossed band across the midsection, and a second one that runs across the back.

Pull it on and the line is smooth from the first second, under a shirt, a blazer, a fitted dress. It sits flat, it doesn’t ride up, and the seamless knit means nothing shows through.

What it does

  • Holds your midsection evenly, never pinches
  • One smooth line under close-fitting clothes
  • A crossed band across the back you feel the moment you slouch
  • Knitted relief, not printed. Nothing to crack or peel
  • Short fitted sleeves, no bunching under a sleeve
  • Soft, breathable, thin enough to disappear under a shirt

Seamless knit. Sizes S through 5XL.

Our 3D shaping lines are knitted straight into the fabric and cross the stomach, the waist and the lower back, exactly where soft tissue shifts most. Why does that matter? Because a stomach looks fuller not only from fat, but from the way loose tissue sits and moves under clothes. By holding those areas evenly, the T-shirt redistributes them into one smooth line and takes the volume out of your middle. Combined with gentle 360° compression, the shaping works from the first second and lasts as long as you wear it.

  • Targeted 3D shaping lines across the belly and waist
  • A flat stomach from the second you pull it on
  • Gentle 360° compression: holds without squeezing
  • Crossed back band for an upright, confident posture
  • Soft, breathable and stretchy fabric, invisible under clothes

K
Kathleen Z.
Really pleased with this

Comfortable, flattering and the shaping through the arms is exactly what I hoped for.

C
Carla T.
Ordered a second one

I wore the first one so often that I bought a backup in the same size. It smooths my upper arms without feeling tight.

L
Lisa M.
Great everyday top

Goes with everything and the fit stays neat all day. My arms look more even under it.

E
Erin V.
Good shaping, a wriggle to put on

The first thirty seconds are a struggle, but once it is on it is comfortable and smooth.

S
Shannon D.
Better than I expected

I ordered without much hope and was surprised. The knit holds everything gently and the black looks smart.

H
Heather L.
Nice quality fabric

Thicker than a normal tee but still soft. It has kept its shape after several washes.

P
Paloma A.
It smooths my upper arms

The area I am most self-conscious about looks much more even. Simple as that.

S
Sonia V.
Feels supportive

Like a light hug around the arms and waist. I forget I am wearing it after ten minutes.

M
Melissa G.
Lovely top, slightly warm

The knit is thicker than a normal tee so I keep it for cooler days. The shaping is excellent.

P
Phoebe S.
Good under jackets

No bulk and no rolling. It sits flat under a blazer and gives a clean line.

A
Andrea V.
I wear it constantly

It has become the top I grab when I want to feel put together with no effort.

M
Madison A.
Flattering cut

The seams sit in the right places and the shape follows the body without clinging.

K
Keisha L.
Washes well

Cold wash, air dry, no loss of stretch so far. Still as supportive as on day one.

O
Olivia U.
Great fit, needs more colours

Black is useful, but I would buy two more shades tomorrow.

F
Freya I.
Confident in short sleeves

The first fitted T-shirt in years that I feel comfortable in. The sleeves make a real difference.

E
Ella S.
Holds its shape

Even after a long day the fabric has not gone slack or ridden up. Impressed.

H
Hope Y.
Smart casual win

I dressed it up with trousers for dinner and it looked expensive. Comfortable the whole evening.

W
Wendy F.
Discreet shaping

Nobody can tell there is any compression. They just say the outfit suits me.

L
Lucia V.
Smooths well, runs small

Order one size up if you are between sizes. Mine fits nicely now.

C
Claire Z.
My sister wanted one too

She noticed how smooth my arms looked in mine and ordered her own. Both of us are happy.

D
Diana R.
True to the description

It supports, it smooths and it stays comfortable. No surprises.

L
Lauren F.
My arms look softer

The little dimples above my elbows are much less visible. Subtle, but I can see it.

M
Malika W.
Easy to style

Works with jeans, skirts and under knitwear. The black stays deep after washing.

E
Emily D.
Very good, hem could be longer

Another couple of centimetres would be perfect for my torso. Everything else is great.

P
Paige E.
Comfortable compression

Firm without pinching anywhere. I can breathe and eat normally, which was never true of my old shapewear.

K
Kimberly J.
Good for work days

Eight hours at a desk and it never dug in or needed adjusting.

F
Fiona P.
Nice neckline

High enough to feel modest and low enough to look modern.

R
Rania P.
Fully opaque

No see-through issues even when I stretch. That mattered to me.

C
Cassie F.
Nice compression, snug sleeves

The sleeves felt tight for the first hour and then settled. The smoothing is worth it.

J
Julie T.
Feels like quality

Dense knit, neat stitching, no loose threads. It feels like it will last.

A
Amanda V.
Smoother back line

The bra area looks flat underneath, which is the thing I always check in the mirror.

C
Chelsea R.
I stand taller in it

Something about the support makes me hold my shoulders back. An unexpected bonus.

Y
Yasmin J.
Perfect for travel

I packed it for a week away and wore it three times. It does not crease.

M
Mariam Q.
Good product, slow to dry

The thicker fabric takes a while on the line. Otherwise I am very pleased.

NEED HELP ?

Your questions, answered.

Here’s everything you need to know about our product

The raised 3D lines are knitted directly into the fabric and cross over the stomach and the lower back. They hold your midsection evenly the moment you pull the T-shirt on, and the wide band keeps that hold in place while you move.

Absolutely! The Leonie T-shirt is designed for all-day wear. The breathable, seamless knit ensures you'll feel great for hours, at your desk or out.

Not at all! The knit is thin, matte and seamless, so it disappears under a shirt, a blazer or a fitted dress. No seam prints through.

The crossed 3D lines hold the stomach and the sides the second you pull it on, while the wide band redistributes soft areas into one smooth line. The back panel straightens your posture at the same time, and a straighter back alone makes the whole silhouette look longer and leaner.
