REFERENCE · GLOSSARY

Glossary: selling second-hand from A to Z.

The terms around photos, sizes, platforms and rules, briefly explained.

In short

This glossary explains the key terms for anyone selling second-hand clothes: from photo types such as flat lay and ghost mannequin, through sizing such as W/L and petite, to rules such as buyer protection, HMRC platform reporting and the EU AI Act. Every definition is short and needs no prior knowledge.

All terms

AI try-on image
A worn image generated with artificial intelligence from a real photo of the item. It should be labelled as such.
Bundle
Several items sold together, often for a combined price.
Buyer protection
Protection for buyers who pay through the platform. On Vinted, a Vinted fee is added to purchases made with “Buy now”; on eBay it's the eBay Money Back Guarantee, which covers the purchase price and original postage on eligible purchases.
Cover photo
The first photo of a listing. It's the photo buyers see first when they scroll.
Digital platform reporting
Platforms report details about sellers to HMRC. Sellers with fewer than 30 sales of goods a year and a total of €2,000 (about £1,700) or less don't need to be reported.
EU AI Act
EU Regulation 2024/1689. Its transparency duties for AI-generated content have applied since 2 August 2026. It is EU law; the UK is not an EU member.
Flat lay
Clothes photographed flat from above, usually on the floor, a table or a bed.
Ghost mannequin
A photo on a mannequin that is then retouched out, so the item looks as if it holds its shape by itself.
Inside leg
The inner leg length of trousers, measured from the crotch seam to the hem.
Labelling
A note that an image was created with AI, visible in the image or text and machine-readable in the file.
ONO
Or nearest offer. A note in classified listings that the price is open to negotiation.

A size range for shorter women; at Marks & Spencer, for example, for women around 160 cm (5ft 3in): shorter sleeves, legs and body. Each brand sets its own limit.
Pilling
Small bobbles on the surface of fabric, especially on knitwear. Counts as a sign of wear and belongs in the listing.

Tall
A size range for taller women: longer sleeves and legs.
Try-on image
A photo showing an item of clothing worn on a body.
W/L
Jeans sizes in inches: W for waist, L for length (inside leg).
