Shoppers are voicing their frustration due to a modification that led to items being listed as the wrong size.
This online marketplace has altered its measurement guidelines for women's and children's clothes failing to inform all shoppers about the modification.
Social Media Response
Many shoppers and sellers have taken to social media saying Vinted listings now show an altered size classification compared to what was initially listed because of the remapping.
The company said the updated approach better aligns with other platforms.
The platform has recommended to review their products and adjust the sizing manually when needed, which has left users frustrated.
Measurement Approach Updates
Previously, the measurements included numerical and alphabetical indicators, like S/8 or M/10.
The new system has a letter with a size spectrum for example S/UK 8-10.
In some cases, the sizing has been recategorised - for example a size L was previously a 12 but now shows as UK 16-18.
Shopper Accounts
A fashion influencer, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," the way the service now categorizes.
A different member, based in Glasgow, stated items she posted featuring size 14 markings were appearing on the platform as measurements 20-22.
"Should someone sized 20-22 purchase these they may become frustrated," she said.
Necessary Adjustments
Another shopper, from Derby, explained she became annoyed because the modification necessitated personal updates the sizing for "all her products".
"Personally, this is quite irritating, because of my ongoing medical condition and selling on Vinted has been paramount for me since losing part of my income," she said.
Service Background
The service features exceeding 100 million users, including 18 million in the UK.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This represents another occasion where an unanticipated change on the platform has faced criticism: last year, the service retracted a modification regarding delivery choices following member complaints.
