Shoppers are voicing their frustration due to a modification that led to products showing incorrect sizing.
The second-hand shopping app has revised its measurement guidelines for women's and children's clothes failing to inform all shoppers about the modification.
Many shoppers and sellers are posting online saying Vinted listings now show a different size category compared to what was initially listed because of the remapping.
The platform stated the updated approach better aligns with comparable marketplaces.
They have suggested members to examine their items and adjust the sizing manually where appropriate, which has left users frustrated.
Previously, the measurements included numerical and alphabetical indicators, for instance S/8 or M/10.
The new system has a letter with a size spectrum such as S/UK 8-10.
For certain items, the measurements have been reclassified - for example a size L used to be a 12 but currently displays as UK 16-18.
One content creator, 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," as the platform currently indicates.
Stephanie Gallen, located in Scotland, stated items she posted on Vinted with size 14 labels were showing in the marketplace as size 20–22.
"Should someone sized 20-22 purchase these they're going to be very disappointed," she stated.
Another shopper, located in England, said she had been left angered by the change as she had to manually change the sizing for "all her products".
"Personally, this is quite irritating, as I'm chronically ill and platform income has been essential after experiencing income reduction," she said.
The app has more than 100 million shoppers, comprising 18 million UK members.
It has become a favored option to second-hand platforms like eBay and Depop.
This isn't the first time that an unexpected update within the service has received backlash: earlier, the platform withdrew an update concerning shipment methods due to shopper criticism.
