I have a large black caviar quilted tote I just LOVE, but it's getting up there in age and the corners are starting to wear, the chain is losing its luster and the gold plating on the logo clasp is coming off. I'd love to restore it to its old glory, but don't know if Chanel can do the repairs on the corners, how long they will take and how much they will cost. Does anyone have any experience with this? Also, the zipper was replaced a while back, but not by Chanel. Will they have a problem with this? Someone told me LV won't do repairs on a bag that's been repaired elsewhere unless they can repair that part too. Does anyone have any experience sending their caviar bag to a good repair shop or is it best just to go straight to the source? Thanks so much!!!!
