In all honesty, I'm not sure that $1000+ gets you any more than say, $500+ in terms of quality except from maybe Hermes, however, I think those prices are ridiculous. They may be timeless and beautiful but really, I don't think that there is any handbag truly worth $10,000. They are great, but not *that* great if that makes sense.
Don't get me wrong, my collection is mainly Chanel, some YSL and the occassional LV so I love bags like most on here. Just thinking "logically" though, I don't see a difference in quality in my $600 Speedy vs. my other bags that were over $1000.
