Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
The second-hand shopping app has revised its measurement guidelines for female and kids' apparel without notifying all shoppers about the modification.
Social Media Backlash
Countless users and merchants are expressing on platforms saying Vinted listings now show a modified sizing category versus the original listing as a result of the reclassification.
Vinted explained the revised method more closely matches other platforms.
They have suggested members to review their products and manually change the size when needed, resulting in member annoyance.
Sizing System Updates
Previously, the sizing featured a single numeric size and a letter, like S/8 or M/10.
The new system has a letter and a range like S/UK 8-10.
In some cases, the size labels have been reassigned - for example a size L was formerly size 12 but currently displays as UK 16-18.
User Accounts
Frankie Bridger, who makes TikTok content about plus-size fashion, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," as the platform currently indicates.
A different member, from Glasgow, stated items she posted on Vinted with size 14 labels were displaying on the service as larger sizing 20-22.
"Should someone sized 20-22 purchase these they may become frustrated," she stated.
Manual Updates
Charlotte Lunn, located in England, stated she felt frustrated by the change as she had to manually change the sizing for "all her products".
"For me this is particularly frustrating, because of my ongoing medical condition and platform income has been essential for me since losing part of my income," she stated.
Marketplace Information
The service features exceeding 100 million users, comprising 18 million UK members.
It has emerged as a preferred choice versus similar marketplaces including eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: previously, Vinted reversed a change regarding delivery choices due to shopper criticism.
