I need your expert advice! I posted a similar post before but I just want to get your expertise! I received my first balenciaga city (black) but I realized SA accidentally sent me 06 instead of 07. The one I received..the leather seems thin, but then again it's my first B Bag so I really can't be sure. If it's too thin, will it affect the strength of the bag? Because I plan to carry it a lot. Since it's black it can't be that much diff from 06 to 07..right? Should I exchange it? I just want to make the right decision so I don't regret it later on! Thanks so much!
