Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
The popular resale platform has altered its measurement guidelines for women's and children's clothes failing to inform all shoppers about the modification.
Online Platforms Reaction
Many shoppers and sellers are expressing on platforms saying Vinted listings now show a modified sizing category than originally posted due to the recalibration.
The platform stated the revised method more closely matches other platforms.
It has advised users to check their listings and manually change the size if necessary, resulting in member annoyance.
Sizing System Changes
Previously, the measurements included one number and one letter, like S/8 or M/10.
The revised method features a letter and a range like S/UK 8-10.
For certain items, the size labels have been reassigned - for example a size L was previously a 12 but is now a UK 16-18.
Shopper Experiences
A fashion influencer, who produces content about larger sizing, explained the modification "makes transactions more difficult".
"Few clothing companies classify XL as 20-22," which is what Vinted now does.
Another user, located in Scotland, stated items she posted on Vinted with size 14 labels were appearing on the platform as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she said.
Manual Updates
A different user, based in Derby, explained she became annoyed by the change as she had to manually change the measurements for "each individual item".
"For me this is particularly frustrating, because of my ongoing medical condition and platform income has been essential for me since losing part of my income," she said.
Marketplace Information
The service features exceeding 100 million shoppers, comprising 18 million UK members.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This represents another occasion that an unexpected update to the app has proved unpopular: earlier, the platform withdrew an update regarding delivery choices due to shopper criticism.
