Members of the platform have expressed outrage after an update resulted in products showing incorrect sizing.
The second-hand shopping app has revised its measurement guidelines for female and kids' apparel but did not contact all shoppers about the modification.
Online Platforms Backlash
Countless users and merchants are posting online saying Vinted listings now show a different size category versus the original listing due to the recalibration.
The platform stated the updated approach better aligns with comparable marketplaces.
They have suggested members to review their products and adjust the sizing manually where appropriate, resulting in member annoyance.
Measurement Approach Changes
Previously, the measurements included one number and one letter, for instance S/8 or M/10.
The revised method features a letter with a size spectrum such as S/UK 8-10.
In some cases, the sizing has been recategorised - for example a size L used to be a 12 but is now a UK 16-18.
User Experiences
One content creator, who creates plus-size fashion videos, stated the update "complicates both purchasing and selling".
"Not many brands say XL is a 20-22," as the platform currently indicates.
Stephanie Gallen, based in Glasgow, said garments she listed with size 14 tags were appearing on the platform as measurements 20-22.
"Should someone sized 20-22 purchase these they're going to be very disappointed," she explained.
Manual Updates
Charlotte Lunn, based in Derby, said she had been left angered because the modification necessitated personal updates the measurements for "each individual item".
"This situation is especially annoying, because of my ongoing medical condition and selling on Vinted has been paramount following partial earnings loss," she said.
Service Background
The app has more than 100 million members, comprising 18 million UK members.
It has emerged as a preferred choice to second-hand platforms like eBay and Depop.
This is not the initial instance where an unanticipated change on the platform has faced criticism: previously, the platform withdrew an update regarding delivery choices due to shopper criticism.
