So, I just bought a real person purse (my longstanding current purse is a canvas bag with owls on it and a giant inkstain) from the Kate Spade sale, and I need to know if I should put like leather protectant on it or something. I carry a backpack to and from work, so this would mostly be a weekend/evening purse, but since I spent more money on it than I usually spend on a purse, I would like it to not get ruined fast. It's the buttery soft pebbled leather, and I don't know if I can use anything on it to protect it from the elements. Any advice? I know at least some of you are fancier than I am and probably have experience with this stuff.
