Been using my Jane for the past two weeks and I love it. For me it's more delicate in the sense that I don't want to put too much in it since it's just being held up by the two straps the way the bag is designed, it might put too much strain if I filled it up and made it all boxy since the straps aren't center on it (if you get what I mean).
And anyway, I don't like the way it looks boxy.. I adore the way it slouches when it's not full

I think it's a fantastic bag and I love using it!! Light weight, stylish.. reasonable size.. not too heavy.. can't get any more perfect than that!
