I have the Gucci mini Marmont in dusty rose and I love the way it looks. But I HATE that it's just a little too small to fit my phone, card holder and keys. And the small Marmot is too big (I'm such a goldilocks). I'm thinking of getting the medium Lou camera bag, but looking for your thoughts on durability? I used my Marmont almost every day and it's still in amazing condition. This would be my first YSL so would love your thoughts/reviews!!
