Shoppers are voicing their frustration after an update resulted in products showing incorrect sizing.
This online marketplace has revised its measurement guidelines for women's and children's garments but did not contact all shoppers about the modification.
Social Media Backlash
Numerous buyers and vendors are posting online saying Vinted listings now show a different size category than originally posted because of the remapping.
Vinted explained the new system was more in line with similar services.
They have suggested members to examine their items and adjust the sizing manually when needed, which has left users frustrated.
Size Classification Changes
Previously, the sizing featured numerical and alphabetical indicators, such as S/8 or M/10.
The revised method features an alphabetical indicator and numerical range like S/UK 8-10.
With some products, the sizing has been recategorised - for example a size L used to be a 12 but now shows as UK 16-18.
Member Stories
One content creator, who makes TikTok content about plus-size fashion, stated the update "complicates both purchasing and selling".
"Not many brands say XL is a 20-22," as the platform currently indicates.
A different member, from Glasgow, explained products she uploaded featuring size 14 markings were displaying on the service as larger sizing 20-22.
"Should someone sized 20-22 purchase these they will likely be quite upset," she explained.
Necessary Adjustments
A different user, located in England, stated she felt frustrated because the modification necessitated personal updates the sizes on "every single listing".
"This situation is especially annoying, because of my ongoing medical condition and platform income has been essential following partial earnings loss," she stated.
Service Background
The platform boasts over 100 million users, comprising 18 million UK members.
It has become a favored option to second-hand platforms like eBay and Depop.
This represents another occasion where an unanticipated change to the app has proved unpopular: earlier, Vinted reversed a change to its shipping options due to shopper criticism.
