You have a beautiful collection - we have similar taste. Your photos are very nice. They really show some lovely detail of your collection. I love the graphitti zippi and the Roses line. I hope one day to pick up such beautiful pieces.
And Edia, I think that the larger Milla (mine is the larger one) is big enough for going out IF your mom can go out without a wallet. Milla doesn't fit a wallet (my ZCP is too big), but there is a pocket for cards and some cash maybe. So that isn't a problem for me. It can hold the cards and the cash, some makeup, a cell phone, keys... The essentials. So I think it's a good choice! And a beautiful one too! :)
And hey, I have to tell you guys something - I have a new bag! This time I'm cheating on Louis with Balenciaga!
