Vinted users have been reacting angrily due to a modification that led to listings displaying inaccurate size information.
The popular resale platform has updated its measurement guidelines for female and kids' apparel failing to inform all users about the change.
Countless users and merchants have taken to social media claiming that product pages now present a different size category versus the original listing as a result of the reclassification.
Vinted explained the updated approach better aligns with other platforms.
They have suggested members to check their listings and adjust the sizing manually when needed, resulting in member annoyance.
Before the change, the sizing featured numerical and alphabetical indicators, for instance S/8 or M/10.
The updated approach includes a letter with a size spectrum like S/UK 8-10.
With some products, the sizing has been recategorised - like an L measurement was formerly size 12 but currently displays as UK 16-18.
Frankie Bridger, who makes TikTok content about plus-size fashion, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," as the platform currently indicates.
Stephanie Gallen, located in Scotland, stated items she posted featuring size 14 markings were displaying on the service as larger sizing 20-22.
"If buyers measuring 20-22 acquire them they may become frustrated," she stated.
Another shopper, located in England, said she had been left angered because the modification necessitated personal updates the measurements for "each individual item".
"Personally, this is quite irritating, as I'm chronically ill and selling on Vinted has been paramount after experiencing income reduction," she explained.
The app has more than 100 million shoppers, comprising 18 million UK members.
It has proved a popular alternative versus similar marketplaces including eBay and Depop.
This isn't the first time that an unexpected update on the platform has faced criticism: last year, the platform withdrew an update regarding delivery choices due to shopper criticism.
