Shoppers are voicing their frustration after an update resulted in listings displaying inaccurate size information.
The second-hand shopping app has updated its size classifications for women's and children's clothes but did not contact all shoppers about the modification.
Countless users and merchants have taken to social media saying Vinted listings now show an altered size classification compared to what was initially listed as a result of the reclassification.
The platform stated the updated approach better aligns with other platforms.
The platform has recommended to review their products and manually change the size when needed, resulting in member annoyance.
Previously, the measurements included one number and one letter, for instance S/8 or M/10.
The updated approach includes an alphabetical indicator and numerical range such as S/UK 8-10.
With some products, the size labels have been reassigned - for example a size L was previously a 12 but now shows as UK 16-18.
A fashion influencer, who produces content about larger sizing, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," the way the service now categorizes.
Another user, from Glasgow, explained products she uploaded on Vinted with size 14 labels were displaying on the service as larger sizing 20-22.
"If buyers measuring 20-22 acquire them they're going to be very disappointed," she stated.
Charlotte Lunn, based in Derby, said she had been left angered because the modification necessitated personal updates the measurements for "each individual item".
"For me this is particularly frustrating, as I'm chronically ill and platform income has been essential following partial earnings loss," she explained.
The platform boasts over 100 million users, with 18 million British users.
It has become a favored option to second-hand platforms like eBay and Depop.
This is not the initial instance when a surprising modification on the platform has faced criticism: previously, Vinted reversed a change regarding delivery choices after backlash from users.
