Vinted users have been reacting angrily due to a modification that led to products showing incorrect sizing.
This online marketplace has altered its size classifications for female and kids' apparel without notifying all shoppers about the modification.
Numerous buyers and vendors are expressing on platforms saying Vinted listings now show an altered size classification compared to what was initially listed due to the recalibration.
The company said the new system was more in line with comparable marketplaces.
It has advised users to examine their items and adjust the sizing manually where appropriate, resulting in member annoyance.
Earlier, the sizes had both numerical and alphabetical indicators, for instance S/8 or M/10.
The revised method features a letter and a range like S/UK 8-10.
For certain items, the measurements have been reclassified - for example a size L used to be a 12 but currently displays as UK 16-18.
Frankie Bridger, 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.
A different member, based in Glasgow, explained products she uploaded on Vinted with size 14 labels were showing in the marketplace 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, explained she became annoyed because the modification necessitated personal updates the sizing for "all her products".
"For me this is particularly frustrating, because of my ongoing medical condition and Vinted sales have been crucial after experiencing income reduction," she said.
The platform boasts over 100 million members, with 18 million British users.
It has emerged as a preferred choice compared to resale services such as eBay and Depop.
This is not the initial instance that an unexpected update on the platform has faced criticism: earlier, the platform withdrew an update regarding delivery choices due to shopper criticism.
