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 but did not contact all shoppers about the modification.
Online Platforms Response
Numerous buyers and vendors have taken to social media claiming that product pages now present a modified sizing category than originally posted as a result of the reclassification.
The platform stated the revised method more closely matches other platforms.
They have suggested members to check their listings and manually change the size when needed, which has left users frustrated.
Sizing System Updates
Earlier, the measurements included a single numeric size and a letter, such as S/8 or M/10.
The updated approach includes a letter and a range such as S/UK 8-10.
For certain items, the size labels have been reassigned - for example a size L was formerly size 12 but now shows as UK 16-18.
Shopper Experiences
Frankie Bridger, who creates plus-size fashion videos, stated the update "complicates both purchasing and selling".
"Not many brands say XL is a 20-22," which is what Vinted now does.
Another user, from Glasgow, stated items she posted featuring size 14 markings were appearing on the platform as measurements 20-22.
"If anyone [who is] size 20-22 buys them they may become frustrated," she said.
Manual Updates
Another shopper, located in England, explained she became annoyed by the change as she had to manually change the sizes on "every single listing".
"This situation is especially annoying, because of my ongoing medical condition and Vinted sales have been crucial for me since losing part of my income," she said.
Service Background
The service features exceeding 100 million members, including 18 million in the UK.
It has emerged as a preferred choice versus similar marketplaces including eBay and Depop.
This is not the initial instance that an unexpected update to the app has proved unpopular: last year, the service retracted a modification to its shipping options after backlash from users.
