Most merch product descriptions fail in the same way: they describe the product rather than selling it. "100% cotton tee, screen printed graphic, unisex fit." That's a specification, not a description. It answers none of the questions that actually convert a browser into a buyer — how will this feel, how will this fit, what does wearing this say about me, and why should I spend $65 on it right now?

Here's a framework for writing product descriptions that answer those questions.

The four things a good merch description does

1. Describes the physical experience of the product. Fabric weight, hand feel, how it drapes, how it fits. "A 260gsm heavyweight cotton that sits differently to a standard tee — substantial in the hand, structured on the body, drapes cleanly without clinging." That tells the buyer what they're actually getting before they can feel it.

2. Communicates the fit clearly. Fit is the biggest source of doubt and the biggest driver of returns. "Relaxed fit, unisex. Model is 178cm and wears a size M for an oversized look. Runs true to size — if you're between sizes and prefer a fitted feel, size down." That description converts size uncertainty from a reason not to buy to a clearly navigated decision.

3. Tells the product's story. Where does this fit in the brand's world? Why this colourway, why this placement, why this design? "We started with the question of what a tee would look like if it stayed in your wardrobe for five years. The answer was this: a heavyweight blank in bone, a mark that you'd wear without thinking twice." That's a story, not a specification. Stories create desire.

4. Handles the practical questions upfront. Sizing, care, delivery timeline — answer these before the buyer has to ask. Unanswered practical questions at checkout create hesitation that costs conversions.

The structure that works

Opening line: the product's essential character in one sentence. Not the product name repeated, not a list of features — the thing that makes this product worth wanting. "The tee we've been building toward since the first drop."

Body: physical description (fabric, weight, construction), fit note (with model sizing), design story (why this design, what it references, what it means). Two to four sentences each.

Details section: fabric composition, weight (in GSM), wash care, sizing guide or link. Presented as a structured list, not prose.

The vocabulary that works for creator merch

Language that signals quality and consideration: heavyweight, substantial, considered, relaxed, structured, softened, washed, worn-in, enduring.

Language to avoid: premium (overused to meaninglessness), luxury (implies a different market tier than most creator merch occupies), unique (the most overused word in product copy), high-quality (a claim that should be demonstrated, not asserted).

Brand-specific language: use the vocabulary your brand has established in your content. If your Instagram voice is relaxed and conversational, your product descriptions should be too. If it's editorial and considered, carry that into the copy. A product description that sounds like a different brand to the account that's selling it creates a subtle cognitive dissonance that buyers notice even if they can't articulate it.

Sizing information: non-negotiable

Include a model shot with stated model measurements and the size they're wearing. Include a size chart with actual garment measurements (chest, length, sleeve) rather than just S/M/L/XL. Include a note on fit (true to size, relaxed, recommend sizing down/up) based on honest feedback from wearers.

Returns are expensive. A buyer who has enough information to order the right size is a buyer who doesn't return. The few minutes it takes to write accurate sizing information pays for itself in reduced returns and increased confidence at checkout.
