I voted for the MC black noe too- just a gorgeous bag, and since you already have mono and damier pieces, this would expand your collection nicely. Second choice would be a Mini Lin speedy. Do you prefer shoulder or handheld bags?
My husband got me the Tulum PM for Valentines Day and it is wonderful. I can't say enough good things about it. Luxury and practical in one great handbag. Who can ask for more !!!!
