“We'd wear it for ten years.” The founding rule, explained.

The rule is written in black marker on the back of a taped-up fabric swatch that still hangs above the cutting table. It is not elegant. The "I" in "ten" is a little crooked. But it is the sentence that decided, long before we knew what we were making, what Chammica's would be.

"We'd wear it for ten years."

Nine words. No exceptions clause, no asterisk. When we wrote them in the spring of 2014, we had one machine, two people, and a tiny room on the second floor of a building on Ashford Lane. We did not yet have a name for the label, a single finished piece, or any idea that we would still be answering to those words a decade later. We thought it was a promise we were making about clothing. We understand now it was really a promise about how we would spend our time.

What the rule actually asks

The rule sounds modest. It isn't. Unpacked honestly, it asks three different questions of every piece we consider making, and a piece has to answer yes to all three before it gets a pattern, let alone a production run.

1. Will the fabric survive? Not just laundering, but years of it. Will the knit pill? Will the colour flatten? Will the weave soften in a way that feels earned, or just tired?
2. Will the shape still read? Ten years is long enough for several cycles of whatever is fashionable right now. If a silhouette only works because of a trend, it will read as costume the moment the trend turns. We ask whether the cut would have been quietly correct in 2014 and would still be quietly correct in 2034.
3. Will we still want to be seen in it? This is the hardest. It is the one no spec sheet can answer. It requires someone to stand in front of a mirror, hold the piece up, and be honest.

“We measure a piece not by how it looks on day one, but on day one thousand. Most of what we reject is beautiful. It is just not durable in the way we need it to be.” — From the studio notebook, July 2017

The year it almost cost us the studio

In our second year we were offered a contract that would have quadrupled our revenue overnight. A department store wanted a capsule line, made faster and cheaper than we had ever produced, finished in fabric we had not chosen. The numbers made sense. The rule did not allow it. We said no, and spent four months wondering whether we had been naive.

We were not naive. We were slower, and for a while poorer, but the name meant something at the end of those four months that it would not have meant if we had signed. The rule had done what it was supposed to do — it had made the hard decision for us before we had the chance to talk ourselves into the easy one.

What it has quietly changed

Twelve years in, the rule has done more than steer product decisions. It has shaped who we hire, how we source, and how we write to each other in the margins of fit notes. It has made us allergic to novelty for its own sake. It has made us careful about the word "new". It has made us argue less about what is on trend and more about what will still feel right to put on a Tuesday morning in 2035.

Most of all, it has changed the way we think about scale. We launch two collections a year, not twelve. Our catalogue has grown by roughly thirty pieces in the past decade, not three hundred. A wardrobe built the way we build it is, by design, small. The rule insisted on that before we understood we needed it to.

What it doesn't ask

The rule is quiet about some things, deliberately. It does not ask whether a piece is innovative. It does not ask whether it will go viral. It does not ask whether it will earn us a write-up. Those questions are not uninteresting — they are simply the wrong first questions, and we have found that when you ask the right first question, the others tend to answer themselves well enough.

If anything has surprised us, it is how rarely the rule creates tension with what works commercially. Pieces built to last ten years tend to earn loyalty. Loyalty compounds. A studio of our size does not need a thousand customers who buy once. It needs a few thousand who come back.

The rule, going forward

We have been asked, occasionally, whether we will ever soften the rule to let in a faster collection, a capsule for a season, a one-off for a collaboration. The honest answer is no. Not because the rule is sacred — we are not precious — but because we have watched, many times, what happens to labels that start making exceptions for themselves.

So the swatch stays taped to the wall. The marker is fading a little. The next time we replace it, we will write the same nine words in the same careful, slightly crooked hand. And everything we make between now and then will have had to pass through them first.
