I'm kinda an amateur about LV so could any1 please help me with some questions? Thanks! 1) Do all the bags in LV have the same color leather and LV logo? 'Cos I saw some leathers that are darker than others. And some logos are brown while others are greenish. 2) What causes your bags to look shiny and "glazed" looking? I know its shiny when you buy it, but it gets shinier as you use it. How do you speed up this process? 3) Are all LV zippers the same? 4) How do you prevent your bag from losing its shape? Thanks!
