The easy assumption is that the whole industry is lazy, or simply does not care. Neither is true, and the real answer is more interesting.
A size 44 woman is not taller than a size 34 woman. Girth and height are close to uncorrelated.
So if a house graded length upward with size, it would hand its longest garment to its widest customer, who might be 158 cm. Leaving length flat across the range is not laziness. Given the size system that exists, it is the least wrong option available.
The only real fix is a separate height axis, which runs directly into the next problem.
Adding petite and tall triples the line count. Fourteen styles across six sizes is 84 lines. With a height axis it becomes 252. Every one of those carries a factory minimum per colourway, a warehouse slot, its own photography and its own markdown risk.
Unsold inventory is the single largest cost in this industry. That is why the petite and tall specialists stay small, and why the biggest of them collapsed. Nobody failed to think of it. The economics punish it hard.
Four people hold four pieces of it and none of them holds the decision.
| who | what they own | why they cannot fix it |
|---|---|---|
| The technical designer | how the garment is drafted and graded | knows all of this in their bones, and has neither budget nor authority |
| The merchandiser | margin, line count, markdown | every fix damages both of the numbers they are judged on |
| E-commerce | conversion and returns | returns are booked as a logistics cost, not against the product that caused them |
| The creative director | the photograph | casts for how the clothes hang, which means tall |
The person who understands it cannot decide. The person who decides has no reason to care.
Return reason codes are blunt instruments. Did not fit. Changed my mind. Nobody in the building can say that one particular style cost forty thousand euros in length returns last season, because the data does not join up well enough to tell them.
No attribution, no business case, no budget. The silence is a missing measurement rather than a shrug.
Factories work to a tolerance, commonly a centimetre on length and more on girth. A brand that publishes 108 cm and ships 106.5 has technically mis-described its own product. Publishing body measurements rather than garment measurements is vaguer and therefore safer.
And that tolerance applies to this site too, so I should say it plainly. Our inputs carry it. It does not undo the work, because the effect we are measuring runs to six or fifteen centimetres of hem travel and the tolerance is one, but it is there and I would rather you heard it from me.
A house’s patterns descend from a block drafted around a fit model of a particular height, sometimes the same woman for fifteen years. Change the block and loyal customers notice within one season. Brands are rationally conservative about the one thing that makes them recognisable on a body, and I do not blame them.
Conversion is counted at the moment of purchase. The return lands in a different column, next month, belonging to someone else.
Telling a customer that a midi will read as a maxi on her costs a sale today and saves a return in three weeks, and those two numbers are not owned by the same person. The customer who buys the wrong thing, returns it, and quietly stops shopping there is far more expensive than the one who was told the truth and bought something else, but that is an argument to be won internally rather than a point anyone concedes unprompted.
Nothing here asks anyone to add a line, raise a minimum, change a block, or argue with a creative director. No new stock. No new photography.
Just this: describe the range you already have, accurately. Every garment in that warehouse already has a length. Somebody measured it, wrote it down, and filed it where the person who most needs it will never see it.
That is the whole proposal, and it is why I built the tool rather than writing a petition.
