Vinted users have been reacting angrily following a change that caused items being listed as the wrong size.
The popular resale platform has updated its measurement guidelines for female and kids' apparel failing to inform every member regarding the update.
Online Platforms Backlash
Many shoppers and sellers are posting online saying Vinted listings now show a modified sizing category than originally posted because of the remapping.
Vinted explained the updated approach better aligns with comparable marketplaces.
They have suggested members to check their listings and update the measurements by hand if necessary, which has left users frustrated.
Size Classification Modifications
Previously, the measurements included one number and one letter, such as S/8 or M/10.
The new system has a letter with a size spectrum such as S/UK 8-10.
In some cases, the sizing has been recategorised - such as a large size was previously a 12 but currently displays as UK 16-18.
Member Stories
One content creator, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Few clothing companies classify XL as 20-22," as the platform currently indicates.
A different member, from Glasgow, explained products she uploaded on Vinted with size 14 labels were displaying on the service as measurements 20-22.
"If anyone [who is] size 20-22 buys them they're going to be very disappointed," she said.
Required Changes
A different user, based in Derby, said she had been left angered due to the update requiring manual adjustment the sizes on "every single listing".
"For me this is particularly frustrating, since I have chronic health issues and selling on Vinted has been paramount following partial earnings loss," she explained.
Marketplace Information
The app has more than 100 million members, comprising 18 million UK members.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This represents another occasion when a surprising modification within the service has received backlash: previously, the service retracted a modification to its shipping options after backlash from users.
