Vinted users have been reacting angrily after an update resulted in listings displaying inaccurate size information.
The popular resale platform has updated its sizing categories for women's and children's garments but did not contact all users about the change.
Numerous buyers and vendors are expressing on platforms stating that platform listings now display a modified sizing category than originally posted because of the remapping.
The platform stated the revised method more closely matches comparable marketplaces.
The platform has recommended to review their products and adjust the sizing manually when needed, resulting in member annoyance.
Before the change, the measurements included a single numeric size and a letter, such as 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 - such as a large size was formerly size 12 but currently displays as UK 16-18.
A fashion influencer, who produces content about larger sizing, stated the update "complicates both purchasing and selling".
"Not many brands say XL is a 20-22," which is what Vinted now does.
Another user, from Glasgow, said garments she listed featuring size 14 markings were appearing on the platform as size 20โ22.
"Should someone sized 20-22 purchase these they may become frustrated," she stated.
Charlotte Lunn, located in England, stated she felt frustrated because the modification necessitated personal updates the measurements for "each individual item".
"For me this is particularly frustrating, because of my ongoing medical condition and platform income has been essential for me since losing part of my income," she explained.
The service features exceeding 100 million users, with 18 million British users.
It has emerged as a preferred choice versus similar marketplaces including eBay and Depop.
This isn't the first time when a surprising modification within the service has received backlash: previously, the service retracted a modification to its shipping options following member complaints.
