# Starting a shirt brand with AI

> Every guide answers this with a workflow — background removal, upscaling, print prep, niche research. That workflow is the part that was supposed to disappear.

Search this and you get a stack. Midjourney for the art, something else for background removal,
an upscaler, a mockup tool, a print-prep checklist, then niche research. Eight steps, a
subscription at four of them, and a warning that raw output "isn't a finished product."

That advice is accurate about the world it was written in. It's also a description of a job
nobody wanted — and most of it has already stopped existing.

## What do you actually need to start a shirt brand now?

Something specific to say, and someone specific to say it to.

That's not a motivational answer, it's what's left after subtraction. The old list had two halves:
a **production** half — resolution, cut-outs, color, file prep, minimum orders, stock — and a
**judgment** half: what this is, who it's for, why anyone would wear it rather than a different
shirt.

The production half is gone. It's the half every guide is still teaching, because it's the half
that's teachable.

## Isn't the AI part the hard part?

The AI part is the commodity part, and treating it as the achievement is the most common way to
end up with a store nobody visits.

Everyone reading this can produce a competent image. That was true a year ago and it's more true
now. So a good-looking graphic is the floor, not the edge — which is why the "funny cat shirt"
graveyard exists: those designs aren't badly made, they're addressed to nobody.

What still separates work is what it's *about*. A wolf is a wolf. The specific ridge your running
club calls The Wall, drawn the way people who've run it would recognise, is not available anywhere
else and can't be prompted by someone who wasn't there.

## What happened to background removal, upscaling, and print prep?

They stopped being steps.

Bringing an image here means bringing the file. Separating the artwork from whatever square it
arrived on, sizing it for the press, and getting the colour to behave on the fabric you picked are
handled on this side. There's no export preset to choose, no DPI to set, no transparent PNG to
produce — and asking a model for a transparent background usually damages the file anyway.

That's one paragraph rather than a chapter, which is the point: half of every competing guide is
instructions for work that has already been absorbed.

## What's actually scarce, then?

Two things, and neither is production.

**Specificity.** The narrower the reference, the stronger the object. A shirt legible to four
hundred people and meaningless to everyone else is a better product than one that's mildly
agreeable to everybody, because the four hundred will actually want it. Generic is the failure
mode that AI made cheap to reach.

**Distribution.** If making costs nothing and producing carries no risk, the scarce step is
somebody seeing the thing. That was always true; it used to be hidden behind the inventory
problem, because you couldn't get far enough to discover it.

Which means the effort has moved. Time spent on the twelfth variation of a graphic is time not
spent on who this is for and where they already gather.

## How small can the audience be?

One, and that's a real answer rather than a consolation.

Nothing is held as stock — each piece is produced after it's bought — so a design that sells twice
costs the same to carry as one that sells two thousand times: nothing. There's no minimum order
and no run to fill.

That removes the question every previous era forced you to answer first: *would enough people want
this?* You can now make the thing for the eleven people it's for, and find out whether it's
actually four hundred.

## What does a first collection look like?

Three to five pieces that share a treatment and differ in subject.

One design is a product; several related ones read as a point of view, and a point of view is what
people follow. Holding the palette and the technique constant while varying what each piece is
*of* is what makes a set legible as a set — and it gives a visitor something to choose between
rather than a single yes-or-no.

It also makes the result interpretable. Five pieces that vary along one axis tell you which axis
mattered; five unrelated pieces that flop tell you nothing.

## What does it cost to be wrong?

An evening.

That number is the whole structural change, and it's worth sitting with. Under the old model,
testing an idea meant buying a hundred units, so you tested one or two and committed hard to
whichever you picked. The correct strategy was conviction, because the cost of being wrong was
enormous.

Now the correct strategy is volume of attempts. Publish several, show them to the people they're
for, and let the answer come back. Being wrong cheaply and often beats being right once, and the
people who struggle are usually the ones still budgeting for conviction.

## How does selling work here?

You publish a design and earn when other people buy it.

Your work becomes something anyone can order in their own size and colour, produced to order and
shipped to them. No stock on your side, no fulfilment, no customer service, and no inventory risk —
a design that sells three times costs you nothing more than one that sells three hundred.

## How do I start?

Bring a design to [JustOG](/) — upload it, see it composited on the real garment, and publish it
so other people can buy it.

Designs other people have published are in the [shop](/shop).

The stack was never the brand. It was the toll booth in front of it.
