Shoppers are voicing their frustration due to a modification that led to items being listed as the wrong size.
The second-hand shopping app has altered its measurement guidelines for women's and children's clothes without notifying all shoppers about the modification.
Online Platforms Backlash
Countless users and merchants are posting online claiming that product pages now present an altered size classification than originally posted because of the remapping.
Vinted explained the new system was more in line with similar services.
It has advised users to check their listings and manually change the size if necessary, which has left users frustrated.
Sizing System Modifications
Before the change, the sizes had both numerical and alphabetical indicators, for instance S/8 or M/10.
The updated approach includes a letter with a size spectrum like S/UK 8-10.
In some cases, the size labels have been reassigned - such as a large size used to be a 12 but currently displays as UK 16-18.
User Accounts
Frankie Bridger, who creates plus-size fashion videos, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," which is what Vinted now does.
Another user, based in Glasgow, said garments she listed on Vinted with size 14 labels were displaying on the service as size 20–22.
"Should someone sized 20-22 purchase these they will likely be quite upset," she said.
Necessary Adjustments
Another shopper, located in England, explained she became annoyed by the change as she had to manually change the sizing for "all her products".
"Personally, this is quite irritating, because of my ongoing medical condition and platform income has been essential after experiencing income reduction," she said.
Service Background
The platform boasts over 100 million users, comprising 18 million UK members.
It has proved a popular alternative compared to resale services such as eBay and Depop.
This is not the initial instance when a surprising modification to the app has proved unpopular: last year, Vinted reversed a change regarding delivery choices due to shopper criticism.
