Go by your waist measurement, not your usual clothing size. Between two sizes, take the larger one.
Why it works
Designed to do
three things properly
- 1A smoother line, the moment you put it on
The high waist and the crossed bands spread even pressure across the middle instead of pinching one spot. You see the difference in the mirror straight away, and it lasts exactly as long as you are wearing it. Anyone telling you a garment changes your body in three weeks is selling you something else.
- 2It disappears under your clothes
The edges are bonded flat rather than hemmed, so there is no ridge to read through a knit dress or slim jeans. No lines, no bulge at the waistband.
- 3It does not roll down
Most shapers grip only at the front, which is exactly why they fold over by lunchtime. The bands here carry round to the sides and back, so there is nothing for it to roll against.
The difference
Not all shapewear
works the same way
The failure mode of a cheap shaper is always the same, and it is always the band.
| HoldLine | Ordinary shapewear | |
|---|---|---|
| Where it holds | Front, sides and back | Squeezes the front only |
| Through the day | Stays where you put it | Rolls and slides by lunchtime |
| Under clothes | Bonded flat edges, no ridge | Hemmed edges that read through |
| How it feels | Even pressure, no pinch point | Digs in at the waist |
| Sizes | XS through 5XL, by waist | Stops at XL, by dress size |
Under everything
The whole point is
that you cannot see it
A close knit dress and slim jeans are the two things that catch out every shaper. Those are the two we shot.


Five colours
Black and beige do
most of the work
Beige vanishes under light and white fabric, which black never does. Most people end up with one of each.





The build
The parts that
decide whether it works
- 1The bonded edge
No hem and no elastic ring at the leg opening. A hemmed edge is what prints a line through a fitted skirt.
- 2The high waist
It sits above the natural waist, which is the only way to get a smooth line rather than a shelf at the top of the garment.
- 3How far it gives
The knit stretches a long way and comes back. That is what lets one size cover a real range, and why sizing up is the safe call.
Sizing
Measure your waist,
not your dress size
Measure around the narrowest part of your torso, a couple of inches above the belly button, keeping the tape level.
| Size | Waist (inches) | Waist (cm) |
|---|---|---|
| XS | 24 to 26 | 61 to 66 |
| S | 27 to 29 | 69 to 74 |
| M | 30 to 32 | 76 to 81 |
| L | 33 to 35 | 84 to 89 |
| XL | 36 to 38 | 91 to 97 |
| 2XL | 39 to 41 | 99 to 104 |
| 3XL | 42 to 44 | 107 to 112 |
| 4XL | 45 to 47 | 114 to 119 |
| 5XL | 48 to 50 | 122 to 127 |
Between two sizes, take the larger one. A brief that is too small rolls, and a rolled band is the thing you can see through your clothes.
Our promise
Nothing to risk
We would rather you measured your waist and ordered once than guessed and sent it back. The size chart above is the honest version, and if it is still wrong you have 30 days.
Questions
Everything else
How is this different from a regular shaper?
Most shapers compress the front of the waist and nothing else, which is why they fold over and why they flatten one spot rather than giving a line. The crossed bands here carry round to the sides and back, so the pressure is even and there is nothing for the band to roll against.
Will it show under my clothes?
The edges are bonded flat rather than hemmed, so there is no ridge at the leg or the waist. Under a ribbed knit dress, which is the hardest test, it does not read. Under something very thin and very pale, the colour matters more than the seam, so take beige.
Does the effect last after I take it off?
No. It is a garment, not a treatment. It gives you a smoother line while you are wearing it and that is the whole of it. Anyone promising a permanent change from a piece of knitwear is not telling you the truth.
Which size should I order?
Go by the waist measurement in the chart above, not by your usual clothing size. Between two sizes, take the larger one.
Can I wear it all day?
Yes. It is meant to feel like firm underwear rather than a corset. If it is pinching or leaving deep marks, it is too small and you should size up.
What is it made of and how do I wash it?
A soft stretch knit with bonded edges. We have not confirmed the exact fiber percentages with the maker, so we are not going to print a number we cannot stand behind. Cool wash, hang to dry, no dryer. The dryer is what kills the stretch.
What if it is not right?
Thirty days, money back. This is also why the second one is free: most people want one on and one in the wash, and it means a colour you are unsure about costs you nothing to try.
A smooth line that stays put
Crossed bands front, sides and back. Nine sizes by waist measurement, and the second one free.
