Shoppers are voicing their frustration after an update resulted in products showing incorrect sizing.
The second-hand shopping app has altered its sizing categories for female and kids' apparel without notifying all shoppers about the modification.
Numerous buyers and vendors are expressing on platforms stating that platform listings now display a modified sizing category than originally posted due to the recalibration.
Vinted explained the updated approach better aligns with similar services.
It has advised users to examine their items and update the measurements by hand if necessary, resulting in member annoyance.
Before the change, the sizes had both numerical and alphabetical indicators, like S/8 or M/10.
The new system has an alphabetical indicator and numerical range for example S/UK 8-10.
With some products, the measurements have been reclassified - like an L measurement used to be a 12 but now shows as UK 16-18.
A fashion influencer, who makes TikTok content about plus-size fashion, stated the update "complicates both purchasing and selling".
"Few clothing companies classify XL as 20-22," the way the service now categorizes.
Stephanie Gallen, from Glasgow, said garments she listed on Vinted with size 14 labels were showing in the marketplace as size 20–22.
"If buyers measuring 20-22 acquire them they're going to be very disappointed," she explained.
Charlotte Lunn, from Derby, stated she felt frustrated by the change as she had to manually change the measurements for "each individual item".
"For me this is particularly frustrating, since I have chronic health issues and selling on Vinted has been paramount after experiencing income reduction," she stated.
The app has more than 100 million shoppers, including 18 million in the UK.
It has emerged as a preferred choice to second-hand platforms like eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: last year, the service retracted a modification to its shipping options due to shopper criticism.
