Members of the platform have expressed outrage after an update resulted in items being listed as the wrong size.
The popular resale platform has altered its sizing categories for female and kids' apparel but did not contact every member regarding the update.
Numerous buyers and vendors are posting online claiming that product pages now present an altered size classification than originally posted due to the recalibration.
The platform stated the revised method more closely matches similar services.
The platform has recommended to review their products and update the measurements by hand when needed, which has left users frustrated.
Before the change, the sizing featured a single numeric size and a letter, for instance S/8 or M/10.
The revised method features a letter and a range like S/UK 8-10.
For certain items, the size labels have been reassigned - such as a large size was formerly size 12 but is now a UK 16-18.
Frankie Bridger, who makes TikTok content about plus-size fashion, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," the way the service now categorizes.
Another user, located in Scotland, explained products she uploaded with size 14 tags were appearing on the platform as larger sizing 20-22.
"If anyone [who is] size 20-22 buys them they will likely be quite upset," she explained.
Another shopper, from Derby, explained she became annoyed by the change as she had to manually change the sizes on "every single listing".
"Personally, this is quite irritating, because of my ongoing medical condition and platform income has been essential following partial earnings loss," she stated.
The app has more than 100 million users, comprising 18 million UK members.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This represents another occasion that an unexpected update within the service has received backlash: earlier, Vinted reversed a change to its shipping options following member complaints.
