Hi! I'm new purse forum and (and the luxury market in general!). I have a pre-loved Batignolles Horizontal (my first LV), and I'm eyeing a Galleria PM. I just love the shape of that bag. Can LV replace the strap, even though it's an older bag that's discontinued? Any idea of the ball park cost? I have no experience with this, and welcome any advice. Thanks so much!
