Members of the platform have expressed outrage following a change that caused listings displaying inaccurate size information.
This online marketplace has altered its size classifications for female and kids' apparel but did not contact all shoppers about the modification.
Numerous buyers and vendors are expressing on platforms claiming that product pages now present a different size category compared to what was initially listed as a result of the reclassification.
The company said the new system was more in line with similar services.
It has advised users to check their listings and adjust the sizing manually if necessary, resulting in member annoyance.
Before the change, the measurements included one number and one letter, for instance S/8 or M/10.
The revised method features an alphabetical indicator and numerical range like S/UK 8-10.
In some cases, the size labels have been reassigned - like an L measurement was previously a 12 but now shows as UK 16-18.
One content creator, who produces content about larger sizing, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
A different member, based in Glasgow, stated items she posted on Vinted with size 14 labels were displaying on the service as size 20–22.
"Should someone sized 20-22 purchase these they will likely be quite upset," she stated.
Another shopper, based in Derby, said she had been left angered because the modification necessitated personal updates the sizing for "all her products".
"This situation is especially annoying, since I have chronic health issues and selling on Vinted has been paramount after experiencing income reduction," she explained.
The platform boasts over 100 million users, comprising 18 million UK members.
It has become a favored option to second-hand platforms like eBay and Depop.
This is not the initial instance that an unexpected update within the service has received backlash: last year, the service retracted a modification regarding delivery choices due to shopper criticism.
