Members of the platform have expressed outrage following a change that caused products showing incorrect sizing.
The second-hand shopping app has updated its measurement guidelines for women's and children's clothes but did not contact all shoppers about the modification.
Digital Channels Backlash
Numerous buyers and vendors are posting online claiming that product pages now present an altered size classification compared to what was initially listed due to the recalibration.
The platform stated the updated approach better aligns with similar services.
They have suggested members to review their products and adjust the sizing manually where appropriate, resulting in member annoyance.
Sizing System Changes
Earlier, the sizes had both one number and one letter, for instance S/8 or M/10.
The new system has an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the sizing has been recategorised - like an L measurement was formerly size 12 but now shows as UK 16-18.
Member Experiences
Frankie Bridger, who makes TikTok content about plus-size fashion, said the change "makes both selling and buying harder".
"Rarely do manufacturers list XL as sizes 20-22," as the platform currently indicates.
A different member, from Glasgow, explained products she uploaded featuring size 14 markings were appearing on the platform as larger sizing 20-22.
"Should someone sized 20-22 purchase these they're going to be very disappointed," she said.
Manual Updates
Charlotte Lunn, located in England, said she had been left angered due to the update requiring manual adjustment the measurements for "each individual item".
"This situation is especially annoying, because of my ongoing medical condition and platform income has been essential after experiencing income reduction," she explained.
Platform Context
The service features exceeding 100 million users, including 18 million in the UK.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This is not the initial instance that an unexpected update to the app has proved unpopular: last year, the platform withdrew an update to its shipping options following member complaints.
