Vinted users have been reacting angrily after an update resulted in items being listed as the wrong size.
The second-hand shopping app has revised its sizing categories for women's and children's clothes but did not contact 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 because of the remapping.
The company said in a post on its website that the new system was more in line with other platforms. It has advised users to check their listings and manually change the size if necessary, which has left users frustrated.
Vinted said in a statement on its website that it was changing the sizing system to make shopping on the app "easier than ever".
