Vinted users have been reacting angrily after an update resulted in products showing incorrect sizing.
This online marketplace has altered its sizing categories for women's and children's clothes failing to inform all users about the change.
Many shoppers and sellers have taken to social media saying Vinted listings now show a different size category than originally posted as a result of the reclassification.
Vinted explained the revised method more closely matches other platforms.
They have suggested members to review their products and adjust the sizing manually if necessary, resulting in member annoyance.
Before the change, the sizes had both numerical and alphabetical indicators, like S/8 or M/10.
The revised method features a letter with a size spectrum like S/UK 8-10.
In some cases, the sizing has been recategorised - such as a large size was previously a 12 but is now a UK 16-18.
One content creator, who creates plus-size fashion videos, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Stephanie Gallen, based in Glasgow, explained products she uploaded on Vinted with size 14 labels were appearing on the platform as larger sizing 20-22.
"If anyone [who is] size 20-22 buys them they may become frustrated," she explained.
Another shopper, from Derby, explained she became annoyed due to the update requiring manual adjustment the sizes on "every single listing".
"For me this is particularly frustrating, since I have chronic health issues and platform income has been essential for me since losing part of my income," she explained.
The service features exceeding 100 million users, including 18 million in the UK.
It has become a favored option compared to resale services such as eBay and Depop.
This is not the initial instance where an unanticipated change to the app has proved unpopular: last year, the service retracted a modification regarding delivery choices after backlash from users.
