Vinted users have been reacting angrily following a change that caused listings displaying inaccurate size information.
This online marketplace has updated its sizing categories for women's and children's clothes without notifying every member regarding the update.
Countless users and merchants are posting online claiming that product pages now present a modified sizing category compared to what was initially listed due to the recalibration.
Vinted explained the new system was more in line with comparable marketplaces.
The platform has recommended to review their products and update the measurements by hand where appropriate, causing user dissatisfaction.
Earlier, the sizing featured numerical and alphabetical indicators, such as S/8 or M/10.
The updated approach includes a letter with a size spectrum such as S/UK 8-10.
In some cases, the measurements have been reclassified - like an L measurement was previously a 12 but now shows as UK 16-18.
Frankie Bridger, who produces content about larger sizing, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," as the platform currently indicates.
A different member, from Glasgow, stated items she posted featuring size 14 markings were showing in the marketplace as measurements 20-22.
"If anyone [who is] size 20-22 buys them they will likely be quite upset," she said.
Charlotte Lunn, from Derby, stated she felt frustrated because the modification necessitated personal updates the sizing for "all her products".
"For me this is particularly frustrating, since I have chronic health issues and platform income has been essential after experiencing income reduction," she said.
The platform boasts over 100 million members, comprising 18 million UK members.
It has proved a popular alternative versus similar marketplaces including eBay and Depop.
This isn't the first time that an unexpected update to the app has proved unpopular: earlier, Vinted reversed a change regarding delivery choices due to shopper criticism.
