Shoppers are voicing their frustration after an update resulted in products showing incorrect sizing.
This online marketplace has revised its size classifications for women's and children's garments failing to inform every member regarding the update.
Countless users and merchants are expressing on platforms saying Vinted listings now show a different size category compared to what was initially listed as a result of the reclassification.
Vinted explained the updated approach better aligns with comparable marketplaces.
The platform has recommended to check their listings and manually change the size if necessary, resulting in member annoyance.
Earlier, the sizes had both one number and one letter, such as S/8 or M/10.
The updated approach includes a letter with a size spectrum like S/UK 8-10.
With some products, the size labels have been reassigned - like an L measurement used to be a 12 but is now a UK 16-18.
Frankie Bridger, who makes TikTok content about plus-size fashion, 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, stated items she posted with size 14 tags were showing in the marketplace as larger sizing 20-22.
"If buyers measuring 20-22 acquire them they may become frustrated," she said.
Another shopper, located in England, said she had been left angered because the modification necessitated personal updates the sizes on "every single listing".
"For me this is particularly frustrating, since I have chronic health issues and platform income has been essential for me since losing part of my income," she said.
The service features exceeding 100 million shoppers, comprising 18 million UK members.
It has proved a popular alternative compared to resale services such as eBay and Depop.
This is not the initial instance where an unanticipated change within the service has received backlash: earlier, Vinted reversed a change concerning shipment methods following member complaints.
