Hi all I'm new to Marc Jacobs bags so please fill me in on the info I'm so excited to start collecting and I just want to know if MJ bags age well and hold up well in the long run? I have a coworker who says that he's bought several MJ bags for his gf and two of them have had stitching come undone, which resulted in having to return the bags. This worries me a bit... Since I'm crazy about my new Stam, I'd like to know how durable it is and if I should be extra careful with it. Do let me know please Thanks!
