Vinted users have been reacting angrily due to a modification that led to items being listed as the wrong size.
This online marketplace has revised its sizing categories for female and kids' apparel failing to inform all shoppers about the modification.
Countless users and merchants are expressing on platforms stating that platform listings now display a modified sizing category than originally posted because of the remapping.
The platform stated the updated approach better aligns with similar services.
It has advised users to examine their items and manually change the size where appropriate, resulting in member annoyance.
Previously, the sizes had both numerical and alphabetical indicators, like S/8 or M/10.
The revised method features a letter with a size spectrum like S/UK 8-10.
With some products, the size labels have been reassigned - such as a large size was formerly size 12 but currently displays as UK 16-18.
A fashion influencer, who produces content about larger sizing, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Stephanie Gallen, from Glasgow, said garments she listed with size 14 tags were appearing on the platform as measurements 20-22.
"If anyone [who is] size 20-22 buys them they're going to be very disappointed," she said.
A different user, based in Derby, said she had been left angered due to the update requiring manual adjustment the measurements for "each individual item".
"For me this is particularly frustrating, since I have chronic health issues and Vinted sales have been crucial following partial earnings loss," she explained.
The service features exceeding 100 million users, including 18 million in the UK.
It has proved a popular alternative compared to resale services such as eBay and Depop.
This is not the initial instance where an unanticipated change on the platform has faced criticism: earlier, the service retracted a modification concerning shipment methods after backlash from users.
