I bought a pair of trousers on Vinted. Described simply as size 12, very good condition. Photos included a pic of the label showing the size '12R' (R=regular) but no measurements. They're quite a popular brand so if you know these, you know which size / product number to buy - both of which are shown on the label.
When they arrived they'd likely been altered to be exceptionally short (so short that they were actually capri style on my standard height 5'5" self). To the best of my knowledge, this particular trouser isn't available in a cropped length (and the product number on the label corresponds with the standard length I'd expected as I already own several pairs of these) but I messaged the seller to ask if they were cropped or altered as there was nothing mentioned in the listing to say they weren't a standard length. Seller replied 'no - these are normal length, 29 inches inside leg'.
I whipped out my tape measure and measured them - 24 inches. I sent this photo to the seller to show that the trousers is received were most definitely not 29 inches and could I please return for refund because they are far too short. She said no.
I put in a claim with Vinted (item significantly not as described) and sent photos showing the 'regular label' as well as the seller's message about them being standard length.
Vinted replied to say sorry, there was no fault from the seller and that I should have asked more questions before buying to make sure that they were suitable and to check that hadn't been altered.
AIBU to think that if you are selling trousers that you've altered or are not full length, you mention this when selling them?
They weren't cheap either (£50) so I'm quite out of pocket as the chance of selling them on in such an odd length is almost impossible.
