Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
The popular resale platform has revised its measurement guidelines for women's and children's garments but did not contact all shoppers about the modification.
Digital Channels Response
Many shoppers and sellers have taken to social media stating that platform listings now display an altered size classification than originally posted because of the remapping.
The platform stated the updated approach better aligns with similar services.
The platform has recommended to check their listings and update the measurements by hand where appropriate, resulting in member annoyance.
Measurement Approach Modifications
Before the change, the measurements included numerical and alphabetical indicators, for instance S/8 or M/10.
The new system has a letter and a range such as S/UK 8-10.
In some cases, the measurements have been reclassified - such as a large size used to be a 12 but currently displays as UK 16-18.
User Stories
A fashion influencer, who creates plus-size fashion videos, explained the modification "makes transactions more difficult".
"Not many brands say XL is a 20-22," as the platform currently indicates.
Another user, from Glasgow, explained products she uploaded with size 14 tags were showing in the marketplace as larger sizing 20-22.
"If buyers measuring 20-22 acquire them they're going to be very disappointed," she stated.
Required Changes
Another shopper, from Derby, stated she felt frustrated due to the update requiring manual adjustment the sizes on "every single listing".
"Personally, this is quite irritating, because of my ongoing medical condition and platform income has been essential after experiencing income reduction," she explained.
Marketplace Information
The platform boasts over 100 million shoppers, including 18 million in the UK.
It has proved a popular alternative to second-hand platforms like eBay and Depop.
This isn't the first time when a surprising modification within the service has received backlash: earlier, the platform withdrew an update concerning shipment methods following member complaints.
