Members of the platform have expressed outrage following a change that caused items being listed as the wrong size.
The second-hand shopping app has updated its size classifications for women's and children's garments failing to inform all users about the change.
Online Platforms Reaction
Many shoppers and sellers have taken to social media stating that platform listings now display a modified sizing category than originally posted as a result of the reclassification.
Vinted explained the revised method more closely matches comparable marketplaces.
They have suggested members to examine their items and adjust the sizing manually when needed, resulting in member annoyance.
Size Classification Updates
Before the change, the sizes had both one number and one letter, such as S/8 or M/10.
The revised method features an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the measurements have been reclassified - like an L measurement was previously a 12 but is now a UK 16-18.
Member Stories
A fashion influencer, who makes TikTok content about plus-size fashion, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Another user, based in Glasgow, said garments she listed with size 14 tags were appearing on the platform as larger sizing 20-22.
"If anyone [who is] size 20-22 buys them they may become frustrated," she stated.
Required Changes
Charlotte Lunn, located in England, stated she felt frustrated due to the update requiring manual adjustment the measurements for "each individual item".
"This situation is especially annoying, as I'm chronically ill and Vinted sales have been crucial following partial earnings loss," she stated.
Marketplace Information
The platform boasts over 100 million members, with 18 million British users.
It has become a favored option compared to resale services such as eBay and Depop.
This isn't the first time when a surprising modification to the app has proved unpopular: previously, the service retracted a modification to its shipping options due to shopper criticism.
