Members of the platform have expressed outrage after an update resulted in products showing incorrect sizing.
The second-hand shopping app has updated its sizing categories for women's and children's garments without notifying all shoppers about the modification.
Online Platforms Reaction
Many shoppers and sellers have taken to social media saying Vinted listings now show a different size category compared to what was initially listed due to the recalibration.
The company said the revised method more closely matches comparable marketplaces.
They have suggested members to review their products and adjust the sizing manually when needed, which has left users frustrated.
Sizing System Modifications
Earlier, the sizing featured one number and one letter, such as S/8 or M/10.
The revised method features a letter and a range like S/UK 8-10.
In some cases, the size labels have been reassigned - such as a large size was previously a 12 but now shows as UK 16-18.
User Accounts
One content creator, who creates plus-size fashion videos, explained the modification "makes transactions more difficult".
"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 showing in the marketplace as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she stated.
Manual Updates
Charlotte Lunn, based in Derby, said she had been left angered because the modification necessitated personal updates the sizes on "every single listing".
"Personally, this is quite irritating, since I have chronic health issues and platform income has been essential for me since losing part of my income," she explained.
Marketplace Information
The app has more than 100 million users, comprising 18 million UK members.
It has become a favored option compared to resale services such as eBay and Depop.
This represents another occasion where an unanticipated change within the service has received backlash: last year, Vinted reversed a change to its shipping options after backlash from users.
