Members of the platform have expressed outrage due to a modification that led to listings displaying inaccurate size information.
This online marketplace has revised its size classifications for women's and children's clothes without notifying all shoppers about the modification.
Social Media Backlash
Many shoppers and sellers are posting online saying Vinted listings now show a different size category versus the original listing as a result of the reclassification.
The company said the updated approach better aligns with other platforms.
They have suggested members to examine their items and manually change the size when needed, resulting in member annoyance.
Measurement Approach Modifications
Before the change, the measurements included a single numeric size and a letter, like S/8 or M/10.
The revised method features an alphabetical indicator and numerical range for example S/UK 8-10.
With some products, the sizing has been recategorised - such as a large size was formerly size 12 but currently displays as UK 16-18.
User Accounts
One content creator, who produces content about larger sizing, explained the modification "makes transactions more difficult".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Stephanie Gallen, from Glasgow, said garments she listed with size 14 tags were showing in the marketplace as size 20–22.
"If buyers measuring 20-22 acquire them they may become frustrated," she said.
Necessary Adjustments
Charlotte Lunn, based in Derby, explained she became annoyed by the change as she had to manually change the sizing for "all her products".
"Personally, this is quite irritating, as I'm chronically ill and Vinted sales have been crucial after experiencing income reduction," she explained.
Platform Context
The platform boasts over 100 million users, including 18 million in the UK.
It has become a favored option to second-hand platforms like eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: last year, the platform withdrew an update regarding delivery choices after backlash from users.
