Shoppers are voicing their frustration after an update resulted in items being listed as the wrong size.
The second-hand shopping app has revised its sizing categories for women's and children's clothes without notifying every member regarding the update.
Digital Channels Response
Many shoppers and sellers are posting online claiming that product pages now present an altered size classification than originally posted as a result of the reclassification.
The company said the updated approach better aligns with comparable marketplaces.
They have suggested members to review their products and manually change the size when needed, causing user dissatisfaction.
Sizing System Updates
Earlier, the measurements included numerical and alphabetical indicators, such as S/8 or M/10.
The revised method features a letter with a size spectrum like S/UK 8-10.
In some cases, the sizing has been recategorised - for example a size L was formerly size 12 but currently displays as UK 16-18.
Shopper Stories
A fashion influencer, who creates plus-size fashion videos, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," as the platform currently indicates.
Stephanie Gallen, based in Glasgow, stated items she posted on Vinted with size 14 labels were showing in the marketplace as larger sizing 20-22.
"If buyers measuring 20-22 acquire them they're going to be very disappointed," she said.
Manual Updates
Charlotte Lunn, from Derby, explained she became annoyed because the modification necessitated personal updates the sizing for "all her products".
"For me this is particularly frustrating, because of my ongoing medical condition and platform income has been essential following partial earnings loss," she explained.
Marketplace Information
The service features exceeding 100 million members, including 18 million in the UK.
It has proved a popular alternative versus similar marketplaces including eBay and Depop.
This represents another occasion when a surprising modification to the app has proved unpopular: earlier, Vinted reversed a change concerning shipment methods after backlash from users.
