I buy what I like and sell what I don't use. Most of my bags are from contemporary designers instead of premiere ones simply because I don't believe the quality is there to justify 4+ times the price like it was ten or more years ago. They almost all feel massed produced now no matter what price, and the ones that don't typically cost more than I'm willing to pay. After sales customer service policies are also getting stingier across the board, but much more so at the premiere level, where you would think customers would be more demanding in that regard.
LV in particular has had a long spiral downward for me this decade. The materials don't feel as luxurious, the bags look like the production was rushed, and they charge 40% to 60% more for that quality as opposed to when their bags were nicer. Also, their satellite stores barely have any selection and their flagship stores feel more like international street bazaars than luxury stores, where I'm competing for service and breathing room instead of getting thoughtful and attentive input from SAs in selecting a bag. Don't even get me started on their collaboration with Supreme

. I haven't purchased anything new from them since Christmas 2014 and I haven't looked back.
I think there's been a deliberate strategy by premiere designers to keep people in certain income brackets from purchasing their goods, so that bags that used to cost $1400 now cost $2500, even as the quality and brand experience has plummeted. Instead of trying to keep up with that racket I've been buying what's easy on the wallet from brands that actually provide decent customer service and after-sales service, and while the labels don't have the same cachet, I think many contemporary bags are up to par with their premiere counterparts in every regard except prestige, which I care about less and less as I mature.
