Measured three times, given three sizes, and still left with red marks? Your size was never the problem.

Linda is 54 and lives just outside Leeds. She's been measured at a big department store on the high street, at an independent shop, and once more on a friend's advice. A 36DD. Then a 34E. Then a 38D.

Every bra came home in a bag with tissue paper. Every bra ended up the same way. The band riding up her back. The wire stabbing under her arm when she reached into the car on the school run with her granddaughter. Straps sawing into her shoulders until she was hooking a thumb under them in the queue at Boots.

And when she finally took it off, the mirror showed it all. Red lines. Dents. Skin that looked like it had been tied up with string.

Like most women, Linda tried everything she was told. A bigger band so it wouldn't cut. It rode up her back. A smaller band so it would stay put. It left a deep groove she could trace with her finger. Bigger cups, smaller cups, 'minimiser', 'full support'. Wider hooks. The loosest hook. The tightest hook.

None of it worked, and here's why. Every one of those bras was built the same way: a wire, two thin straps and a narrow band yanked tight by hooks.

Change the number on the label and you only move where the pressure lands. The wire still presses. The straps still carry all the weight on a strip of elastic. The band still squeezes your back into rolls. A drawer full of 'properly fitted' bras is a drawer full of the same design in different sizes.

Think about where a traditional bra actually holds you. A hard wire under each breast. Two narrow straps on your shoulders. One thin band clamped round your ribs by hooks. That's it. All the weight of a fuller bust, hanging off a few narrow lines.

That's why you get grooves in exactly those places. It's physics, not your figure. Narrow pressure points dig in; wide, soft surfaces spread the load.

After 50, it gets worse. Skin is softer and marks more easily, and a fuller bust or a little more round the middle gives a tight band more to squeeze. So the band bites, the flesh spills out over the top and sides, and the back rolls show through your jumper.

A measuring tape can't fix a design problem. Only a different design can.

The ShapeChic Original Bra takes away every part that was hurting Linda. There's no wire, so nothing stabs under your arm. The lift comes from the shape and the fabric itself.

There are no hooks and no clasps. You pull it on over your head like a vest. No fiddling behind your back, no tight hook-and-eye band clamping your ribs.

The straps are wide and cushioned, so the weight spreads across your shoulders instead of sawing into one line. Full sides gather the spill under your arms. One wide, smooth back panel lies flat and smooths away back rolls. And soft lace cups mean it still looks pretty.

Sizes run from S to 4XL in seven colours.

Look in the mirror after a long stretch in your old bra and you can map every part of it on your skin: a curve under each breast, two dents on the shoulders, a ring round the back.

The ShapeChic leaves nowhere for those marks to come from. No wire, so no curve pressed into you. No hooks, so no clamped band and no row of little dents down your spine. Wide cushioned straps spread the weight across your shoulders, so there's no single strip carrying the load.

Then look at your outline. The full sides hold in what used to spill under your arms. The smooth back panel lies flat, so the rolls that showed through a fine-knit jumper smooth out. The lift stays without a wire digging in. Different design, different result.

For years Linda chose clothes to hide her bra. Baggy tops. Cardigans over everything. Nothing fitted, because fitted showed the rolls, the bulges and the line of the band.

Now she pulls on the soft fitted jumper she'd stopped wearing. No back rolls through the knit. No spill at the sides. A smooth, lifted line that makes her look slimmer, as though she's dropped a couple of dress sizes, and she stands taller because nothing is dragging on her shoulders.

She does the school run, the big shop, a long lunch with her sister, and never once hooks a thumb under a strap.

That's the part she talks about most. Not the bra. The feeling of being comfortable in her own clothes again.

You don't need a fourth fitting. You don't need another 'properly fitted' bra in a new size that cuts in exactly like the last one. The size was never the problem. The wire, the thin straps and the hook-and-eye band were.

Every week you keep wearing them is another week of red grooves, sore shoulders and tops chosen to hide your back.
