Shoppers are voicing their frustration due to a modification that led to items being listed as the wrong size.
The second-hand shopping app has altered its sizing categories for women's and children's clothes failing to inform all users about the change.
Countless users and merchants are expressing on platforms stating that platform listings now display a different size category versus the original listing due to the recalibration.
Vinted explained the revised method more closely matches similar services.
They have suggested members to check their listings and manually change the size where appropriate, which has left users frustrated.
Before the change, the sizing featured one number and one letter, such as S/8 or M/10.
The new system has an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the measurements have been reclassified - 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".
"Few clothing companies classify XL as 20-22," which is what Vinted now does.
Another user, based in Glasgow, said garments she listed with size 14 tags were appearing on the platform as measurements 20-22.
"If buyers measuring 20-22 acquire them they're going to be very disappointed," she stated.
Charlotte Lunn, from Derby, explained she became annoyed due to the update requiring manual adjustment the sizes on "every single listing".
"For me this is particularly frustrating, as I'm chronically ill and Vinted sales have been crucial after experiencing income reduction," she explained.
The service features exceeding 100 million shoppers, comprising 18 million UK members.
It has become a favored option versus similar marketplaces including eBay and Depop.
This represents another occasion where an unanticipated change to the app has proved unpopular: previously, the platform withdrew an update concerning shipment methods due to shopper criticism.
