Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
This online marketplace has altered its size classifications for women's and children's garments but did not contact all users about the change.
Social Media Backlash
Countless users and merchants are expressing on platforms stating that platform listings now display a different size category versus the original listing as a result of the reclassification.
Vinted explained the revised method more closely matches other platforms.
It has advised users to examine their items and manually change the size when needed, which has left users frustrated.
Size Classification Changes
Earlier, the measurements included a single numeric size and a letter, for instance S/8 or M/10.
The updated approach includes a letter with a size spectrum such as S/UK 8-10.
For certain items, the sizing has been recategorised - for example a size L was formerly size 12 but is now a UK 16-18.
User Accounts
A fashion influencer, who produces content about larger sizing, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," as the platform currently indicates.
A different member, based in Glasgow, said garments she listed on Vinted with size 14 labels were showing in the marketplace as size 20–22.
"If anyone [who is] size 20-22 buys them they may become frustrated," she explained.
Required Changes
Another shopper, located in England, stated she felt frustrated due to the update requiring manual adjustment the sizing for "all her products".
"This situation is especially annoying, since I have chronic health issues and platform income has been essential for me since losing part of my income," she said.
Marketplace Information
The platform boasts over 100 million users, with 18 million British users.
It has proved a popular alternative compared to resale services such as eBay and Depop.
This represents another occasion when a surprising modification to the app has proved unpopular: last year, the platform withdrew an update to its shipping options after backlash from users.
