Vinted users have been reacting angrily after an update resulted in items being listed as the wrong size.
This online marketplace has revised its size classifications for female and kids' apparel without notifying every member regarding the update.
Many shoppers and sellers are posting online 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 updated approach better aligns with other platforms.
They have suggested members to review their products and manually change the size when needed, which has left users frustrated.
Before the change, the sizes had both a single numeric size and a letter, for instance S/8 or M/10.
The new system has a letter with a size spectrum like S/UK 8-10.
In some cases, the sizing has been recategorised - for example a size L was previously a 12 but now shows as UK 16-18.
One content creator, who makes TikTok content about plus-size fashion, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," the way the service now categorizes.
A different member, from Glasgow, explained products she uploaded with size 14 tags were showing in the marketplace as measurements 20-22.
"Should someone sized 20-22 purchase these they will likely be quite upset," she explained.
Charlotte Lunn, located in England, explained she became annoyed because the modification necessitated personal updates the sizes on "every single listing".
"Personally, this is quite irritating, as I'm chronically ill and selling on Vinted has been paramount for me since losing part of my income," she said.
The app has more than 100 million users, with 18 million British users.
It has emerged as a preferred choice compared to resale services such as eBay and Depop.
This is not the initial instance when a surprising modification within the service has received backlash: last year, the service retracted a modification regarding delivery choices after backlash from users.
