I am finally thinking of putting in an SO for my first birkin, and I have a few questions for the experts here. 1. I hear 35 can get heavy quickly. I don't do very well with heavy bags. So out of all the leather options, which one is the lightest? 2. Between vert anis and chartreuse, which one is greener, which one is yellower? 3. How are the prices of JPGs compared to 35cm birkins for the same leather and hardware? Many thanks!
