In terms of LV, mine are:
Best: a tie between my (1)
Capucines BB and the (2)
Metis Hobo (so so sooooo saddened that LV discontinued the style a year or so ago, since it's perhaps my most used and functional LV
). A close contender: my
Montsouris MM backpack from 2002, which has gone with me on pretty much every trip I've gone on.
Worst: Definitely the
Neverfull PM. It was my first LV (I bought the Montsouris pre-loved), and it was wayyyy too small for me as a tote (pretty devastating since it was my first, but definitely a lesson learned in doing some prior research before buying designer bags). I ended up selling it, and then bought the MM size, which was much more practical.
And yes, I agree with the OP, the
6 Key Holder is such a great and practical LV purchase on a budget! I had one, but lost it (alongside my keys) a couple years back!
