Members of the platform have expressed outrage following a change that caused items being listed as the wrong size.
The second-hand shopping app has updated 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 modified sizing category than originally posted due to the recalibration.
The platform stated the revised method more closely matches similar services.
It has advised users to review their products and update the measurements by hand where appropriate, resulting in member annoyance.
Size Classification Modifications
Before the change, the sizes had both numerical and alphabetical indicators, such as S/8 or M/10.
The new system has an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the measurements have been reclassified - for example a size L used to be a 12 but now shows as UK 16-18.
Shopper Experiences
A fashion influencer, who creates plus-size fashion videos, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Stephanie Gallen, located in Scotland, said garments she listed featuring size 14 markings were appearing on the platform as size 20–22.
"Should someone sized 20-22 purchase these they may become frustrated," she stated.
Manual Updates
Another shopper, based in Derby, explained she became annoyed because the modification necessitated personal updates the measurements for "each individual item".
"Personally, this is quite irritating, as I'm chronically ill and platform income has been essential for me since losing part of my income," she stated.
Marketplace Information
The app has more than 100 million members, comprising 18 million UK members.
It has become a favored option to second-hand platforms like eBay and Depop.
This is not the initial instance when a surprising modification to the app has proved unpopular: last year, the service retracted a modification to its shipping options following member complaints.
