Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
The popular resale platform has updated its size classifications for women's and children's clothes failing to inform all shoppers about the modification.
Social Media Response
Many shoppers and sellers are posting online stating that platform listings now display an altered size classification versus the original listing because of the remapping.
The platform stated the updated approach better aligns with other platforms.
It has advised users to review their products and update the measurements by hand when needed, resulting in member annoyance.
Sizing System Changes
Before the change, the measurements included numerical and alphabetical indicators, for instance S/8 or M/10.
The updated approach includes a letter and a range for example S/UK 8-10.
For certain items, the sizing has been recategorised - such as a large size was formerly size 12 but currently displays as UK 16-18.
User Stories
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.
A different member, from Glasgow, explained products she uploaded with size 14 tags were displaying on the service as measurements 20-22.
"If buyers measuring 20-22 acquire them they will likely be quite upset," she explained.
Manual Updates
Charlotte Lunn, located in England, said she had been left angered due to the update requiring manual adjustment the measurements for "each individual item".
"This situation is especially annoying, because of my ongoing medical condition and selling on Vinted has been paramount for me since losing part of my income," she stated.
Marketplace Information
The service features exceeding 100 million members, including 18 million in the UK.
It has proved a popular alternative compared to resale services such as eBay and Depop.
This isn't the first time that an unexpected update within the service has received backlash: last year, Vinted reversed a change regarding delivery choices due to shopper criticism.
