Foundations · User Context
One shopper,
one moment.
Who Threadwise is for, where the decision actually happens, and what the research says about why it is hard. Expanded from the target-user section of the Product Source of Truth.
01Who it is for
The sustainability-curious, non-expert shopper. She already reads labels on food and skincare, and wants the same clarity for clothing — without becoming an expert to get it.
User type
Sustainability-curious, non-expert. Reads food and skincare labels; wants the same for clothing.
Goals
Choose better quickly, feel confident in the choice, avoid the guilt of getting it wrong.
Frustrations
Labels she can’t decode, claims she can’t trust, help that is never there when it counts.
Behaviour
Fast and physical. Wants one glanceable answer, and distrusts anything resembling a sales pitch or a lecture.
What she already does
Picks up the garment, turns out the collar, reads the fiber content — then stalls at “80% viscose, 20% elastane.”
What she is not
An activist, a researcher, or someone rebuilding a wardrobe. She is making one decision about one item.
02The decision moment
The whole product lives inside one moment: garment in hand, label visible, a yes-or-no on this one item. Everything about the interface is a consequence of the physical conditions of that moment.
Where
Fitting room, aisle, thrift rack, or a product page online. Increasingly secondhand.
Posture
Standing, one hand free, phone in the other, garment draped over an arm.
Time
Seconds, not minutes. If the answer needs a scroll, it has already failed the shelf.
Conditions
Bad light, a crumpled or faded label, sometimes no signal at all. The tool works offline.
The question
Not “how sustainable is fashion” — just “is this one worth buying?”
After
She buys or skips and moves on. Nothing saved, nothing uploaded, no reason to come back today.
03The decision journey
The arc Threadwise serves runs from doubt, through a calm verdict, to a decision she can act on and move past. The product’s job is to make her feel effective — not to educate her, and not to keep her.
Before · doubt
Powerless at the shelf
Garment in hand, label unreadable, claims untrusted. She wants to choose well but fears getting it wrong — especially on an unbranded or thrifted piece no app can judge.
Feeling: overwhelmedDuring · the read
One honest signal
She types or scans the fiber label. Threadwise returns a calm verdict, a score carrying its “illustrative” cue, and one plain reason — in one breath, with no scroll.
Feeling: orientedAfter · capability
A decision, then out
She buys or skips with confidence, having learned a little about the material. Nothing saved, nothing uploaded. The tool steps back and returns her to the world.
Feeling: capable04What the research says
Four insights, each written as a design directive. Every design choice should walk back up to one of these — or it is decoration.
The barrier is powerlessness, not ignorance
People fail to shop sustainably because they feel their choice does not matter and fear getting it wrong — not because they lack facts.
Implication: the first job is a confident, shame-free verdict that makes her feel effective. Not an education.
They trust the label because brands lie to them
Greenwashing has trained shoppers to distrust brand claims, leaving the legally required content label as the one signal they still believe. Trust is scarce.
Implication: read the label, and openly state that the score is illustrative rather than certified. Honesty is the moat.
The decision is fast, physical, and loneliest where every tool goes blind
It happens standing up, in seconds, and is most acute on the unbranded or thrifted garment that brand-rating tools structurally cannot judge.
Implication: design for the shelf — speed, glanceability, offline — and own the moment no incumbent can follow.
A single score is both what they want and what can hurt them
People crave one glanceable answer, and that same simplicity can mislead, shame, and flatten real nuance.
Implication: deliver the verdict, but calibrate severity honestly, show the facts beneath it, never shame, and gently correct myths.
05Who it is not for
Naming the non-users is what protects the product from becoming a wardrobe manager, a brand database, or a sustainability encyclopedia. Every one of these would dissolve the wedge.
