Shoppers are voicing their frustration due to a modification that led to items being listed as the wrong size.
This online marketplace has revised its measurement guidelines for women's and children's clothes but did not contact every member regarding the update.
Social Media Response
Many shoppers and sellers are expressing on platforms saying Vinted listings now show an altered size classification versus the original listing as a result of the reclassification.
The company said the revised method more closely matches similar services.
It has advised users to examine their items and adjust the sizing manually if necessary, which has left users frustrated.
Measurement Approach Changes
Previously, the sizing featured one number and one letter, such as S/8 or M/10.
The updated approach includes an alphabetical indicator and numerical range like S/UK 8-10.
With some products, the measurements have been reclassified - such as a large size used to be a 12 but currently displays as UK 16-18.
User Experiences
One content creator, who creates plus-size fashion videos, stated the update "complicates both purchasing and selling".
"Rarely do manufacturers list XL as sizes 20-22," which is what Vinted now does.
Another user, located in Scotland, said garments she listed on Vinted with size 14 labels were displaying on the service as measurements 20-22.
"Should someone sized 20-22 purchase these they're going to be very disappointed," she explained.
Required Changes
Another shopper, based in Derby, stated she felt frustrated 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 selling on Vinted has been paramount after experiencing income reduction," she stated.
Marketplace Information
The platform boasts over 100 million users, comprising 18 million UK members.
It has become a favored option compared to resale services such as eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: earlier, the platform withdrew an update to its shipping options following member complaints.
