This is the cheapest conversion fix in Vinted selling and almost nobody does it properly. The size field gives a buyer a label. It doesn't give them certainty, because sizing is genuinely inconsistent — a 12 from one brand is a 14 from another and a 10 from a third, and every experienced secondhand buyer knows this from being burned.
So when they like your fitted dress and there are no measurements, they do the rational thing: they save it 'to think about,' and thinking about it means it's gone. The two numbers that fix this are flat pit-to-pit and length, measured with the garment lying flat, in centimetres, written clearly in the description. Add flat waist and inside leg for trousers.
That's it. Those four numbers answer the question the careful buyer is silently asking — 'will this fit me' — and the careful buyer is the one who completes the sale. There's a second benefit that matters just as much: returns and 'not as described' disputes drop, because a buyer who checked the measurements against a garment they own before buying is not surprised when it arrives.
Those four numbers answer the question the careful buyer is silently asking — 'will this fit me' — and the careful buyer is the one who completes the sale.
You convert the saver and you protect your review score in the same move. The practical change: keep a tape measure where you photograph, and for anything fitted or structured, measure flat before you list. VintSnap drafts the description for you, but the measurements are yours to add — leave a labelled line for them and it becomes a habit rather than an afterthought.
