Symptom first · not measurements

Where it’s actually

going wrong

We don’t ask for your measurements. We ask where it digs in, where it gapes, where it rides up — and tell you which direction to adjust.

Most people who are uncomfortable have no way to find out why, because the only route to an answer has always been walking into a shop and being measured by a stranger. It doesn’t have to be. Every one of these complaints points at a specific dimension, and you can read them yourself.

Nothing selected

Choose a place on the drawing, or pick one from the list under it. Nothing here asks for a measurement and nothing here asks for a photograph.

Start a fit check

Twenty-one things people report, eight places on the garment. Pick the ones that sound like yours.

We never ask for photos of you. Nothing about your body leaves your device.

There is no upload facility here. Not a disabled one, not one that inspects pictures and turns them away — the entry point does not exist. How that works

01 — the method

Three steps, and none of them involve a tape.

01
Mark what's wrong
Tap the places on the drawing, or read the list. Twenty-one complaints across eight parts of the garment. Nothing asks for a measurement and nothing asks for a photograph.
02
Read the direction
Band down a step. Cup up a step. A wider wire. Each one with the reason it follows from what you marked — and, when your marks disagree with each other, we say so instead of picking one.
03
Take it with you
A reference card you can hold up to a mirror or hand to a fitter. Print it, fold it, put it in a pocket. It says what to try, and what would not be answered by trying it.

02 — the position

A direction travels. A number doesn’t.

Two garments with the same figures on the label can be a full step apart in the band, and their wires can differ by more than a centimetre — a measurement that appears on no label anywhere.

So we will not tell you that you are a particular size. We tell you which way to move and why, and that instruction still means something in the next shop, in the next country, in the next brand.

Every arrow is captioned in words as well. Nothing on this service depends on reading a shape or a colour.

03 — the source

Knowledge that has only ever been spoken aloud.

People who develop and make these garments know exactly which complaint belongs to which dimension. It is the most useful thing they know, and it has almost never left the room — passed from one fitter to the next, told to whoever happened to walk in that afternoon.

There was no reason for that except that nobody had written it down in a form a person could use on their own. Bandcheck is that form. Twenty-one complaints, eight parts of the garment, and the reason each one points where it does.

04 — what you get

Everything here is a drawing of a garment. There is nothing else to show.

No photograph of a person appears anywhere on this service, and none ever will. The illustrations are technical flats — the drawings a pattern room makes of a garment lying empty on a table.

Exploded technical detail of one adjustable shoulder strap with its slider and ring, lying flat and empty. — Strap slider · travel direction

Technical detail of a three-row hook-and-eye closure lying flat and empty, with the tightest row marked. — Closure · three rows

Technical detail of a single curved underwire drawn separately from its empty fabric channel. — Wire and channel

Four flat elastic band segments of different lengths stacked as a specimen ladder, with a line joining their end points. — Band lengths · one step apart

Technical detail of the upper edge of an empty cup, showing the elastic binding, the topstitch line and the seam allowance. — Upper cup edge · binding

Sample output

The card you take with you

Two versions of the same reading. The one on the left is what the free plan shows on screen; the one on the right is the print version.

The watermark sits over the directions block and nothing else. The “may not be a fit problem” list and the see-a-doctor notice are never covered, on any plan. A paywall can hold back convenience. It cannot hold back a health notice.

Reference card

Band down, cup up

Technical flat drawing of a bra, back view, lying empty, with the elastic back band, the hook-and-eye closure and two strap sliders drawn in detail.

Direction

The band rides up my back
band downThe band should go down — that is, downward.
A band travels upward when it is longer than the space it has to hold. This is the clearest signal there is.
It only fits on the tightest hook, and it is new
cup upThe cup should go up — that is, upward.
Depth is measured against the band, so taking a band step down without adding a cup step takes away depth you already had.

This may not be a fit problem

A band that only rides up during one specific movement — reaching overhead, driving — is reporting on that movement rather than on its length.
Elastic has a working life. A band that has gone loose after two years has not changed size; it has worn out.

05 — the limits

What this will not do.

Every reading carries this field

This may not be a fit problem

Plenty of these complaints have causes that no change of size will touch: sloped shoulders, a strap placement set by the pattern, elastic that has simply worn out, a cup moulded to a shape that was never yours. Every reading we give names the ones that apply to what you marked. The field is required by the code that produces the reading and can never be empty.

And this one stops the reading entirely

If it hurts

What you're describing isn't something a bra fitting can answer. Please speak to a doctor.

Pain, soreness, numbness, a lump, broken skin, swelling, a change on one side only, anything to do with surgery, recovery, pregnancy or feeding — the service stops and gives no fit guidance at all. On every plan, including the free one.

06 — what it costs

Three plans.

The free plan covers three checks a month, which is enough to work out what is wrong with one garment. Paying removes the limit and unlocks the print version and the cross-brand converter.

The reason to pay is usually the drawer. There are rarely one or two — there are five, they are all slightly wrong in different ways, and every time you change brand the whole comparison starts again. One garment bought wrong costs more than a year of this.

All prices are in US dollars (USD) and include VAT (inkl. MwSt.).

The full comparison

07 — questions

The ones worth asking first.

01What happens to anything I tell you?

This is the question we most want you to read the answer to, so it is first.

We never ask for a photograph of you, of any part of you, or of anything you are wearing. There is no upload button on this service. It is not a disabled button and it is not a filter that inspects pictures and turns them away — the entry point does not exist in the code. Intimate images are among the most damaging categories of personal data there are, and the only reliable protection is not to hold them.

If you choose to use the cross-brand converter and type in a measurement, that number stays in your browser tab. It is not sent to our servers, it is never put in front of a model, it is not attached to any order, it is not used to train anything, and it is gone when you close the tab. The conversion arithmetic runs on your own device.

What you mark in a check is used to produce that reading and is not tied to your account unless you deliberately save it to a record. Nothing you write or mark is used for training.

02Will you tell me what size I am?

No. Not as a limitation we are working on — as a decision.

Sizes are not interchangeable between makers. Two garments labelled identically can differ by a whole step in the band and by more than a centimetre in the wire, which is not written on any label at all. A specific size asserted by a website that cannot see the garment, cannot see you, and has never measured anything would be a guess wearing a number's clothes. When that guess is wrong, we are not the ones who paid for it.

So we give a direction — band down a step, cup up a step, a narrower wire — with the reason it follows from what you marked. A direction survives crossing between brands. A number does not.

03It has been hurting for a long time. What should I do?

What you're describing isn't something a bra fitting can answer. Please speak to a doctor.

Pain is not a fit question, and we will not answer it as one. If you write anything to us that describes pain, soreness, numbness, a lump, broken or irritated skin, swelling, or a change on one side only, this service stops rather than producing a reading. That is deliberate, it is not something that can be switched off, and it applies on every plan including the free one.

The same applies to anything to do with surgery, recovery, pregnancy, feeding, or anyone under eighteen. Those need a person with training, and we have nothing useful to offer.

04How accurate is this, and what is the automated part doing?

The mapping from a complaint to a dimension is long-established knowledge from garment fitting rooms — the sort of thing that gets passed between people who make and sell these things and has never been written down for the people wearing them. It is a general relationship, not a measurement of you.

The automated part reads what you have marked and, if you write a sentence, works out which of those complaints it corresponds to. It does not see you, it does not see the garment, and it produces no sizes. Its output can be wrong, and it should be treated as a starting point for trying things on rather than as a finding.

We never use it for medical, legal, financial, safety, employment, credit, housing or judicial purposes, and nor should you. There is a fuller statement on the AI notice page.

05Can I get a refund, and what about the right of withdrawal?

You have a fourteen-day right of withdrawal on a subscription taken out here, and there is a standard withdrawal form on the withdrawal page.

German law lets that right lapse early for a digital service, but only if three things all happen: you expressly ask us to start before the fourteen days are up, you separately confirm you know the right lapses when we do, and we confirm both of those back to you in writing. At checkout those are two separate boxes, neither of them pre-ticked, and both are re-checked on our side. If all three steps have not happened, your fourteen days continue to run and we will not pretend otherwise.

06How do I cancel, and what happens to my allowance?

There is a cancellation page reachable from the footer of every page. You do not have to sign in to use it, you do not have to speak to anybody, and you will not be shown a discount or an offer to pause on the way through. You will get written confirmation of what was cancelled, when it reached us and when the contract ends.

The allowance included with a plan is a service usage allowance. It is not money, it holds no monetary value, it cannot be cashed out and it cannot be transferred. Unused allowance does not carry over into the next period. There are no top-up packs and no stored balance — if a period runs out, the options are a higher plan or the next period.

07Is there an age restriction?

Yes. This service is for adults. Creating an account requires you to be eighteen or over, and it is set out in the terms of business.

Anything to do with a growing body needs a person, not a website, and this one will decline to answer.

You already know where it goes wrong.

That was always the hard part, and you have had the answer the whole time. Nobody needs to look at you for this.
