I’m not a bag expert by any means but bought a pre-loved Chanel bag before the pandemic hit. Decided to sell it a couple of months ago because I had used it only a handful of times and it just didn’t work for me to be honest, and the resale value was £1000 higher as a result of the subsequent price increases. So I think you can make money on them, even without acting as a ‘collector’/‘investor’.
As a side note, I think price increases are insane and it really puts me off the brand. Also, covid has also taught me that handbags are a bit of a silly thing to spend thousands of pounds on. I know it’s a personal thing
