Hi! I'm new to chanel, and i'm trying to figure out the name of my favorite style...and price. i like the classic quilted chanel flap with the double ccs and the double chain... what is that called? what are the different sizes it comes in and how much do they cost? (i'm confused with their numbering system, 2.55, 2.65, s/m/l, east-west... ) Also, judging from alot of the pics... these bags don't fit alot of stuff..do they? what can you fit in the largest size? thanks alot!!
