Members of the platform have expressed outrage due to a modification that led to listings displaying inaccurate size information.
This online marketplace has altered its size classifications for women's and children's garments failing to inform all shoppers about the modification.
Digital Channels Response
Numerous buyers and vendors have taken to social media stating that platform listings now display an altered size classification than originally posted due to the recalibration.
The platform stated the revised method more closely matches comparable marketplaces.
They have suggested members to review their products and manually change the size when needed, resulting in member annoyance.
Sizing System Updates
Earlier, the sizes had both a single numeric size and a letter, like S/8 or M/10.
The new system has an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the size labels have been reassigned - like an L measurement used to be a 12 but currently displays as UK 16-18.
Shopper Experiences
A fashion influencer, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Not many brands say XL is a 20-22," which is what Vinted now does.
Another user, 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 may become frustrated," she stated.
Manual Updates
A different user, located in England, stated she felt frustrated by the change as she had to manually change the sizing for "all her products".
"Personally, this is quite irritating, because of my ongoing medical condition and platform income has been essential after experiencing income reduction," she explained.
Platform Context
The service features exceeding 100 million users, comprising 18 million UK members.
It has emerged as a preferred choice to second-hand platforms like eBay and Depop.
This isn't the first time that an unexpected update on the platform has faced criticism: last year, the service retracted a modification regarding delivery choices due to shopper criticism.
