Large Mono Musette

I think it's a great size for an everyday bag if you need to carry notebooks or something, though the fact that it doesn't snap shut might be annoying, if the flap flaps around, know what I mean?
 
I own it in Damier... Had it in mono but I'm trying to steer clear of adding anymore mono to my collection unless it's luggage. The Musette is a lovely bag. It wears long enough so that it can cross over the most ample chest yet it still lies nice on the hip. The fact that the flap doesn't snap has never been an issue. The bag is chic!
