I think this is the first season in which there are so many Bow Bags available online. Now, there's a Pomice vesion available as well. An instant classic if you ask me. It first came out two years ago (I my math is correct,) and to this day it's a really nice color. It's never as good as Allumnio but it's available and it's as close as it gets. The only thing I don't like is that it's a light color and I don't like having to baby my bags. As much as I love Miu Miu, I admit I am not very careful with my bags, Miu Miu or not.
