I wear it for 12 hours at the office and completely forget it's there. No rolling down, no marks, no pinching. It's a yes from me.

I've binned four in my life that rolled up under my bust after two hours. This one stays put. All day. It's the first time I've been able to wear shapewear without wanting to rip it off.

What convinced me is that it does NOT roll down. I've been buying shaping briefs for ten years and this is the first one that stays where it should. Thank you DIONA.

Honestly, I expected something that squeezed like a corset. It's just gentle compression, it holds you without suffocating you. I've ordered a second one.

I tried Skims, Honeylove and two other brands before DIONA. None of them gave me such a natural effect with such comfortable support. At this price, it's a no-brainer.

I hadn't worn shapewear in 15 years, too uncomfortable. This DIONA brief I can keep on all day. And the result is there: my waist is defined, my clothes hang better. That's enough to put a smile back on my face.

I was torn between M and L (I'm normally a 12-14). I took my usual size (M) and it's perfect. The size guide is accurate.

Customer service exchanged my brief free of charge when I ordered the wrong size. No return to send back. That's rare these days.

I wore it to a wedding, from 2pm to 1am. No discomfort, no adjusting. That's what really counts.

Mum of two, I wanted my shape back without committing to an hour of exercise I haven't got. This brief does the job. And it's so comfortable I can wear it while I'm running around after the kids.

At my age you stop trying to please everyone. You want to please yourself. This brief helps me do that — without asking me to become someone else.

That dress had been sitting in my wardrobe for three years. Bought "for when I'm ready." My niece's wedding was on the Saturday — I put it on the Thursday evening with the DIONA brief. It did up. It hung properly. It was me. The old me. Without losing a single pound.

Postpartum after my second. That tummy that refused to shift, I'll let you imagine. Three weeks wearing the DIONA every day and my waist is back. I fit into my pre-pregnancy jeans.

Office in the morning, gym at lunch, out in the evening. It keeps up. I wasn't expecting one brief to be that versatile.

I'm 56 with a body that's lived. This brief doesn't try to hide it — it makes the most of it. Waist defined, tummy held. I went out for an important dinner with a confidence I hadn't felt in years. No diet. No effort. Just the right brief.

I never liked seeing myself side on. These days I don't avoid it any more. It changes the whole day.

My husband noticed after three weeks without me saying a word. The mad thing is I wear it every day under my work leggings. Nobody knows. But I know. And that changes everything.

My days are 14 hours long. This brief doesn't shift a millimetre. I completely forget I'm wearing it after ten minutes.

Skinny jeans, bodycon dress, pencil skirt — I've tried it under everything. INVISIBLE. That's why I ordered it in three colours.

Instant flat tummy effect, no joke. I put it on, put my dress on, and my partner noticed straight away. And we've been together eight years.

That bodycon dress, I'd bought it and never worn it. With the DIONA brief underneath, you can't see a thing: no seams, nothing showing. Smooth from head to toe. Now I wear it everywhere.

Instant effect the moment I put it on. My tummy is smooth, my silhouette is more defined. I don't know how that's possible without surgery but I'll take it.

First thing I noticed: my waist redefined. Not slightly. Properly. The mirror doesn't lie.

I'd tried everything. This one is different. My tummy is held in, not crushed. For the first time I looked in the mirror and thought: there I am. I wasn't waiting to lose weight. I was waiting for this brief.
