A Celebrity Lingerie Stylist Says It's Not Your Body. Your Bra Is Making You Look Two Dress Sizes Bigger.

You've just watched me do it, so let me slow it down.

On my mannequin: a fitted ivory jersey dress, the kind most women I dress won't go near. Round its back, a thin black elastic, pulled to the tension of an ordinary bra band. Two soft rolls push straight through the fabric, just below the shoulder blades.

Then I snip it. The dress drops into one smooth line from shoulder blade to waist. I turn it side-on and the front changes too. Same dress. Same shape underneath. The only thing I took away was the band.

I've stood behind thousands of women in fitting rooms who blame their back, their age, their weight. Let me show you what I see from behind.

Every fix women tell me about makes sense. None of them touches the band.

Buying the dress a size up. The rolls don't go anywhere. The dress just hangs off your shoulders and you look bigger, not smaller.

Spanx. It holds for an hour, then rolls down under your bust, and by the time you sit down to eat you can't take a full breath.

The £80 designer bra. Lovely lace, lovely box. Turn it over: the same narrow band, the same underwire. Same rolls, same drop.

Dieting. It comes off your face and hands first. Back fat is the last thing to go, so the rolls stay while you go hungry.

You didn't fail at any of these. Every one fought your body. Not one changed the thing squeezing it.

Here's how I explain it in the studio.

Take a peach-pink balloon. Cinch a thin black elastic round it and it bulges into two lobes, one above, one below. That's your back in a narrow bra band. The soft tissue has nowhere to go but over the edge, and a fitted dress shows every ridge.

Now the front. An underwire is a thin curve of metal. It shapes, but it can't carry the weight of a bust, so the bust sinks to elbow height and your waist seems to start under your arms.

A thin band squeezes your back into rolls and the wire lets your bust drop. Together they make you look two dress sizes bigger in your clothes.

Put the same balloon under a wide band and the lobes vanish. It's the bra, not your body.

That's why I put women in the ShapeChic Original.

Turn it over first. Instead of a strip, the back is one wide piece. The pressure a thin band drives into a single line gets spread across your whole back, so there's no edge for anything to bulge over. Smooth back.

Then the front. There's no wire doing the lifting. The wide band does it, holding the bust up from underneath, all the way round.

Here's the demo from the video. Two grapefruits in a thin mesh bag sag to 30 cm on my tape measure. The same grapefruits under a wide band: 18 cm. Twelve centimetres of lift, with no wire anywhere.

The fabric is soft and seamless, so it disappears under jersey. Sizes run S to 4XL, and the wide band adjusts.

I don't ask women to take my word for it. I put them in front of a three-way mirror.

So here's mine. I'm 55. Same fitted ivory dress, same weight I was this morning. In my old wired bra, two ridges sat across my back and my bust rested at elbow height. Side-on, I looked like a woman squeezed into a dress a size too small.

Black Original on underneath. From behind: one line, shoulder blade to waist. Side-on: bust back up where it belongs, so my waist shows again, right where it should start.

Two dress sizes smaller in the same dress, at the same weight. Not one pound lost. One band changed.

That's the picture my clients send me afterwards. The back they'd given up on, smooth, in a photo they actually keep.

Here's what women tell me they do first.

They take the fitted dress out of the back of the wardrobe, the one they bought for a wedding and spent the whole day hiding under a cardigan. They put it on over the Original and turn side-on in the hall mirror. Then they leave the cardigan on the hook.

At the table, they sit down and breathe. No shapewear rolling under the bust, no wire pressing into the ribs by pudding. Just a soft wide band that stays where it's put.

And when someone takes a photo from the side, they keep it.

That's the part I care about. Not the bra. The woman who stops standing behind her sister in every picture and starts standing beside her.

Go back to that cardigan over the dress. You wore it because you thought your back and your bust were the problem. They weren't. A thin band and a wire were.

You can keep buying dresses a size up and keep deleting the side-on photos. Or you can change the one thing that's been making you look bigger.
