Hi, I'm new to LV and I want to know everything I can about it from choosing to the different terms to maintaining it. I read in other threads about patina, what is patina? If I already know which bag I want, is there anything specific I should check to make sure there is nothing wrong with the bag when I get to the store? Do I need to spray anything on the bag before I use it? Please share with me all the basics and more that I need to know. Thanks in advance!!!!!
