I have worn diesel jeans for 20 years and was in London last week and bought a new pair. When I got them home, I realised they were too big, but I left the UK the next day and travelled to Asia before returning home to Geneva. I asked Diesel if I could exchange the jeans in Geneva (receipts and labels are all available), and it seems that it is not allowed, and I have to return to the UK in order to exchange them! So you have a global brand with global shops, but the only way I can change the jeans is to go back to the UK. Brilliant from a sustainability side! Having worn Diesel for 20 years, I will not not be wearing them again. Not impressed at all, Diesel!!
