Vinted users have been reacting angrily after an update resulted in items being listed as the wrong size.
This online marketplace has updated its size classifications for women's and children's clothes failing to inform every member regarding the update.
Many shoppers and sellers are expressing on platforms stating that platform listings now display 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 similar services.
They have suggested members to review their products and manually change the size where appropriate, resulting in member annoyance.
Previously, the measurements included numerical and alphabetical indicators, such as S/8 or M/10.
The revised method features a letter and a range like S/UK 8-10.
With some products, the measurements have been reclassified - such as a large size was previously a 12 but is now a UK 16-18.
One content creator, who creates plus-size fashion videos, said the change "makes both selling and buying harder".
"Few clothing companies classify XL as 20-22," the way the service now categorizes.
Stephanie Gallen, located in Scotland, stated items she posted featuring size 14 markings were displaying on the service as larger sizing 20-22.
"If anyone [who is] size 20-22 buys them they may become frustrated," she said.
Another shopper, 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 selling on Vinted has been paramount after experiencing income reduction," she said.
The service features exceeding 100 million users, including 18 million in the UK.
It has become a favored option versus similar marketplaces including eBay and Depop.
This represents another occasion that an unexpected update on the platform has faced criticism: earlier, the platform withdrew an update to its shipping options after backlash from users.
