Okay so I never really considered a Neverfull although my girlfriends have been dying for one. I happened to see a monogrammed Neverfull at work. It had purple interior and the ladies initials and I fell in love!! Purple is my favorite color. So my question is, can you buy a pre-loved Neverfull and take it to the store to have it monogrammed, or do you have to buy it brand new that way?
