Vinted users have been reacting angrily 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.
Numerous buyers and vendors are expressing on platforms claiming that product pages now present an altered size classification than originally posted due to the recalibration.
Vinted explained the new system was more in line with similar services.
They have suggested members to review their products and update the measurements by hand where appropriate, resulting in member annoyance.
Before the change, the sizing featured a single numeric size and a letter, for instance S/8 or M/10.
The revised method features a letter and a range such as S/UK 8-10.
With some products, the measurements have been reclassified - for example a size L used to be a 12 but now shows as UK 16-18.
Frankie Bridger, 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, stated items she posted featuring size 14 markings were appearing on the platform as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she explained.
A different user, located in England, said she had been left angered by the change as she had to manually change the measurements for "each individual item".
"This situation is especially annoying, because of my ongoing medical condition and selling on Vinted has been paramount following partial earnings loss," she explained.
The service features exceeding 100 million users, comprising 18 million UK members.
It has emerged as a preferred choice compared to resale services such as eBay and Depop.
This represents another occasion where an unanticipated change to the app has proved unpopular: previously, Vinted reversed a change concerning shipment methods after backlash from users.
