I have a hankering for a 25 cm Birkin in matte lizard for use as an everyday bag. The texture of matte lizard makes it more interesting in the neutral colour I have in mind. However, I like my bags really slouchy. To those who have 25 cm lizard Birkins, could you tell me if your lizard Birkins get slouchy? I understand that lizard and rain do not mix. Does that apply to shiny lizard or matte lizard? Also, do the scales really fall off? Does it make a difference if it is shiny or matte? Thanks!
