Members of the platform have expressed outrage following a change that caused products showing incorrect sizing.
The second-hand shopping app has revised its measurement guidelines for female and kids' apparel without notifying all users about the change.
Digital Channels Response
Many shoppers and sellers are posting online stating that platform listings now display a different size category compared to what was initially listed due to the recalibration.
Vinted explained the new system was more in line with similar services.
It has advised users to review their products and manually change the size if necessary, causing user dissatisfaction.
Sizing System Modifications
Earlier, the sizes had both numerical and alphabetical indicators, such as S/8 or M/10.
The revised method features a letter and a range for example S/UK 8-10.
For certain items, the measurements have been reclassified - such as a large size was formerly size 12 but now shows as UK 16-18.
Member Accounts
Frankie Bridger, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Not many brands say XL is a 20-22," the way the service now categorizes.
A different member, based in Glasgow, explained products she uploaded featuring size 14 markings were displaying on the service as measurements 20-22.
"Should someone sized 20-22 purchase these they will likely be quite upset," she explained.
Necessary Adjustments
Charlotte Lunn, based in Derby, stated she felt frustrated due to the update requiring manual adjustment the measurements for "each individual item".
"This situation is especially annoying, as I'm chronically ill and selling on Vinted has been paramount following partial earnings loss," she said.
Marketplace Information
The service features exceeding 100 million shoppers, comprising 18 million UK members.
It has emerged as a preferred choice to second-hand platforms like eBay and Depop.
This is not the initial instance when a surprising modification within the service has received backlash: earlier, Vinted reversed a change regarding delivery choices after backlash from users.
