Vinted users have been reacting angrily following a change that caused products showing incorrect sizing.
This online marketplace has altered its measurement guidelines for women's and children's garments but did not contact all users about the change.
Numerous buyers and vendors have taken to social media stating that platform listings now display an altered size classification than originally posted as a result of the reclassification.
The company said the updated approach better aligns with other platforms.
They have suggested members to review their products and adjust the sizing manually where appropriate, causing user dissatisfaction.
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 such as S/UK 8-10.
With some products, the sizing has been recategorised - like an L measurement used to be a 12 but currently displays as UK 16-18.
One content creator, who produces content about larger sizing, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," the way the service now categorizes.
Another user, based in Glasgow, said garments she listed featuring size 14 markings were appearing on the platform as measurements 20-22.
"If buyers measuring 20-22 acquire them they may become frustrated," she explained.
Another shopper, located in England, explained she became annoyed due to the update requiring manual adjustment the sizing for "all her products".
"This situation is especially annoying, as I'm chronically ill and selling on Vinted has been paramount for me since losing part of my income," she stated.
The service features exceeding 100 million members, comprising 18 million UK members.
It has become a favored option versus similar marketplaces including eBay and Depop.
This is not the initial instance where an unanticipated change within the service has received backlash: earlier, the service retracted a modification concerning shipment methods following member complaints.
