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 sizing categories for women's and children's clothes but did not contact every member regarding the update.
Social Media Reaction
Numerous buyers and vendors are expressing on platforms saying Vinted listings now show a modified sizing category than originally posted because of the remapping.
Vinted explained the updated approach better aligns with similar services.
It has advised users to examine their items and manually change the size where appropriate, resulting in member annoyance.
Measurement Approach Updates
Earlier, the sizes had both a single numeric size and a letter, like S/8 or M/10.
The new system has an alphabetical indicator and numerical range such as S/UK 8-10.
With some products, the measurements have been reclassified - like an L measurement used to be a 12 but currently displays as UK 16-18.
User Experiences
Frankie Bridger, who produces content about larger sizing, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
A different member, from Glasgow, said garments she listed featuring size 14 markings were showing in the marketplace as larger sizing 20-22.
"Should someone sized 20-22 purchase these they may become frustrated," she said.
Necessary Adjustments
Another shopper, located in England, explained she became annoyed due to the update requiring manual adjustment 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.
Platform Context
The service features exceeding 100 million users, including 18 million in the UK.
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, the platform withdrew an update regarding delivery choices following member complaints.
