Vinted users have been reacting angrily after an update resulted in listings displaying inaccurate size information.
The popular resale platform has revised its size classifications for women's and children's garments failing to inform all users about the change.
Many shoppers and sellers have taken to social media saying Vinted listings now show a different size category versus the original listing as a result of the reclassification.
Vinted explained the revised method more closely matches similar services.
It has advised users to check their listings and manually change the size if necessary, which has left users frustrated.
Earlier, the sizes had both a single numeric size and a letter, for instance S/8 or M/10.
The new system has a letter and a range for example S/UK 8-10.
With some products, the measurements have been reclassified - for example a size L was formerly size 12 but is now a UK 16-18.
One content creator, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Not many brands say XL is a 20-22," the way the service now categorizes.
A different member, located in Scotland, said garments she listed with size 14 tags were displaying on the service as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she said.
Another shopper, located in England, explained she became annoyed because the modification necessitated personal updates the measurements for "each individual item".
"Personally, this is quite irritating, because of my ongoing medical condition and selling on Vinted has been paramount after experiencing income reduction," she stated.
The app has more than 100 million shoppers, with 18 million British users.
It has emerged as a preferred choice versus similar marketplaces including eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: earlier, Vinted reversed a change regarding delivery choices following member complaints.
