A generic nod reads worse than no nod at all

Two coffee tees, same colour, same blank canvas to start from. The left one carries a dense diagram — small labels, specific parts, the kind of thing only somebody who does this work would recognise. The right one carries a script slogan that could sit on any shirt about anything.

Only one of those was made by somebody who knows the group it's for. It isn't the one that looks more finished.

Can you design for a group you're not part of?

Yes, but the work is research, not aesthetics.

Being outside a group doesn't disqualify you from designing for it. What it removes is the shortcut of already knowing the specifics — the tools, the phrases, the jokes that only land inside the group. That's a different job from designing something for a community you already belong to, where the vocabulary is just how you already talk. Without the shortcut, the specifics have to be looked up rather than remembered.

What does the generic version actually look like?

A slogan that's true of the group and true of everyone else too.

"Work hard, stay humble" fits a tradesperson, a nurse, a student, and nobody in particular. It's not wrong about the group — it's just not about them any more than about anyone else, which is the failure a nice script font and a clean layout can't fix.

Why is that worse than not addressing the group at all?

Because it reads as somebody gesturing at them from outside, rather than as silence.

A design that doesn't try to speak to a group is neutral. A design that tries and gets the specifics wrong, or skips them entirely, reads as aimed at the group and missing — which an insider notices immediately, because noticing what's inaccurate about their own trade is easy for them. Specific beats vague for everyone, but the gap is sharpest exactly where the audience knows the subject better than the designer does.

How do you actually learn what a group says?

By reading what they already say to each other, before writing anything new.

Forums, group chats you have access to, the captions under posts people in that group already make — the vocabulary is out there and it's specific in ways an outsider wouldn't guess. A tradesperson doesn't say "hard work," they name the tool, the size, the exact thing that goes wrong on a Tuesday. That noun is worth more than any slogan built around the general idea of the job.

Does research replace actually being in the group?

Not entirely, but it closes most of the gap that matters here.

Lived experience gives you texture research won't — the sound something makes, a stray detail nobody wrote down. But the specific noun, the right in-joke, the tool by its real name: that's findable, and finding it is most of what separates the diagram shirt from the slogan shirt above.

What's the risk of getting a detail wrong anyway?

The shirt reads as an outsider's guess instead of an insider's shirt.

One wrong label, one word used the way an outsider would use it rather than the way the group actually says it, and the whole thing tips from "one of us made this" to "someone looked this up badly." That's a real cost, which is why the research has to be finding the actual people you're designing for and asking, rather than skimming a summary of them.

Why does the specific version get shared more?

Because being seen accurately is the thing people post about.

Nobody shares a shirt that's vaguely about their job. People share the one that gets a detail exactly right, because it proves somebody outside the group bothered to understand it — and that's a more flattering thing to be part of than a slogan that could belong to anyone.

How do I get one made?

Describe what you've learned about the group at JustOG — the specific noun, the actual joke, not the general idea of them. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

The diagram shirt took longer to research. It's the one somebody in that group will actually wear.
