You can see the jacket. You know the fabric, the fit, where the pockets sit. You could describe it to someone in thirty seconds and they would understand exactly what you mean. And then you hit the part nobody warns you about, and that is where most clothing brands quietly end.
A factory cannot cut a garment from a paragraph, or from a photo you liked, or from a moodboard. They need a tech pack: flat drawings from three angles, a chart of every measurement in every size, a list of every material down to the thread, and notes on how each seam is sewn.
That document is the price of entry. Without it you will be ignored, or quoted badly, or sent something that is not what you asked for. And producing it needs skills that take years to learn and were never widely taught.
Pattern cutting, grading, technical drawing, spec writing. That is a college course and a couple of years, before you have made anything.
A freelancer charges around £80 a style and takes days. You need one for every piece, every season, and again every time you change your mind.
Which means your idea now depends on somebody else’s availability, their interest, and their opinion of you.
Notice what none of those options test: whether the idea was any good. The wall has nothing to do with talent. It filters for training, money and contacts — and it has been filtering that way for a hundred years.
Fashion design has never been short of ideas.
It has been short of access.
The gap between an idea and a tech pack was never a creative gap. It was a translation gap — turning ordinary words into the exact technical language a factory reads.
That is the thing generative AI is genuinely good at, and it is why Seamix exists. You describe your piece the way you would describe it to a friend. Seamix does the translation: the drawings, the measurements, the materials, the construction notes, in the order a factory expects them.
You bring the idea. It handles the paperwork.
Seamix was built for both of them, and they need slightly different things from it.
You can draw. What you cannot get back is the day spent typing measurements into a grid, or the week waiting on a spec so you can move on. Seamix does that part in twenty minutes and hands it to you to correct — so the time goes into the design instead of the documentation.
You do not need to draw, and you do not need to know what a grade rule is. Describe what you want to make. You will get a complete pack and, just as usefully, you will see what a real one contains — which is how you learn the language rather than being locked out of it.
It is a big phrase, so here is the small version of it. Anyone who wants to start a clothing brand should be able to. Not anyone with a fashion degree. Not anyone with savings. Anyone with an idea and the will to see it made.
For a century the technical half of this industry has been the gate, and the people it kept out were not short of taste or ideas — they were short of training and money. We would like to find out what gets made when that stops being the deciding factor.
Easier is not the same as careless. Making the process smooth is the point; making it sloppy would waste your money and a factory’s time. So every measurement in a Seamix pack is calculated rather than guessed, twenty-four construction rules run over it before you see it, and every pack is a draft for you to check rather than a finished promise.
Simple to use. Serious underneath. Those two were never in conflict.
Your first tech pack is free. No card, no drawing skills, and nothing to learn before you begin.
