Members of the platform have expressed outrage following a change that caused products showing incorrect sizing.
This online marketplace has revised its measurement guidelines for women's and children's clothes failing to inform all shoppers about the modification.
Online Platforms Backlash
Numerous buyers and vendors are posting online stating that platform listings now display a different size category versus the original listing as a result of the reclassification.
The company said the new system was more in line with other platforms.
The platform has recommended to review their products and manually change the size where appropriate, which has left users frustrated.
Size Classification Updates
Previously, the sizes had both one number and one letter, for instance S/8 or M/10.
The updated approach includes a letter and a range like S/UK 8-10.
For certain items, the size labels have been reassigned - like an L measurement used to be a 12 but is now a UK 16-18.
Member Stories
One content creator, who creates plus-size fashion videos, said the change "makes both selling and buying harder".
"Not many brands say XL is a 20-22," the way the service now categorizes.
Another user, based in Glasgow, said garments she listed on Vinted with size 14 labels were displaying on the service as size 20–22.
"If anyone [who is] size 20-22 buys them they will likely be quite upset," she explained.
Manual Updates
A different user, based in Derby, stated she felt frustrated due to the update requiring manual adjustment the sizing for "all her products".
"For me this is particularly frustrating, since I have chronic health issues and platform income has been essential following partial earnings loss," she explained.
Marketplace Information
The service features exceeding 100 million users, with 18 million British users.
It has become a favored option compared to resale services such as eBay and Depop.
This is not the initial instance that an unexpected update on the platform has faced criticism: last year, the service retracted a modification to its shipping options following member complaints.
