Members of the platform have expressed outrage following a change that caused products showing incorrect sizing.
The second-hand shopping app has revised its sizing categories for women's and children's garments but did not contact all users about the change.
Online Platforms Response
Numerous buyers and vendors have taken to social media saying Vinted listings now show an altered size classification versus the original listing due to the recalibration.
The platform stated the updated approach better aligns with similar services.
It has advised users to check their listings and manually change the size when needed, causing user dissatisfaction.
Sizing System Changes
Before the change, the sizes had both one number and one letter, like S/8 or M/10.
The revised method features a letter with a size spectrum like S/UK 8-10.
With some products, the size labels have been reassigned - such as a large size was formerly size 12 but now shows as UK 16-18.
Member Experiences
A fashion influencer, who creates plus-size fashion videos, explained the modification "makes transactions more difficult".
"Rarely do manufacturers list XL as sizes 20-22," the way the service now categorizes.
Stephanie Gallen, located in Scotland, said garments she listed on Vinted with size 14 labels were appearing on the platform as size 20–22.
"If anyone [who is] size 20-22 buys them they will likely be quite upset," she stated.
Necessary Adjustments
Another shopper, from Derby, said she had been left angered because the modification necessitated personal updates the sizes on "every single listing".
"For me this is particularly frustrating, because of my ongoing medical condition and platform income has been essential following partial earnings loss," she stated.
Platform Context
The app has more than 100 million shoppers, with 18 million British users.
It has emerged as a preferred choice compared to resale services such as eBay and Depop.
This represents another occasion where an unanticipated change within the service has received backlash: last year, the platform withdrew an update regarding delivery choices following member complaints.
