-all Hermes bags except the new Birkin and new Kelly
-Chanel quilted bowler, 2.55, or tote
-Fendi Selleria bags(these always get overlooked, as do most non 'it' Fendi bags, but they are really superb in quality, and timeless in style)
-LV Speedy in epi or monogram (you could burn every other monogram bag that they create, but the speedy gets some kind of reward for making it this long)
-Gucci Jackie O
-Tod's classic totes (mostly every Tod's tote made)
I am not going to try to predict modern bags, because the ones that everyone thought would have turned classic by now have become trendier than when they first came out.
