Vinted users have been reacting angrily following a change that caused products showing incorrect sizing.
The popular resale platform has altered its sizing categories for women's and children's garments but did not contact every member regarding the update.
Numerous buyers and vendors have taken to social media saying Vinted listings now show a different size category compared to what was initially listed as a result of the reclassification.
The company said the revised method more closely matches similar services.
They have suggested members to check their listings and manually change the size where appropriate, which has left users frustrated.
Previously, the sizing featured numerical and alphabetical indicators, like S/8 or M/10.
The updated approach includes an alphabetical indicator and numerical range for example S/UK 8-10.
With some products, the measurements have been reclassified - like an L measurement used to be a 12 but is now a UK 16-18.
Frankie Bridger, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," as the platform currently indicates.
Another user, from Glasgow, said garments she listed featuring size 14 markings were showing in the marketplace as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she said.
A different user, based in Derby, explained she became annoyed because the modification necessitated personal updates the sizing for "all her products".
"For me this is particularly frustrating, since I have chronic health issues and platform income has been essential for me since losing part of my income," she explained.
The app has more than 100 million users, comprising 18 million UK members.
It has emerged as a preferred choice to second-hand platforms like eBay and Depop.
This isn't the first time when a surprising modification within the service has received backlash: earlier, the platform withdrew an update to its shipping options following member complaints.
