I have always said "Louie" -- my grandmother only carried LV bags and she would come over and say something like "Can you put my Louie on the chair." I've complimented others by saying "I love your Louie." I told my hubby "I just ordered a new Louie." Online, I write LV. The other day someone asked me about my "Vuitton" purse and it threw me for a moment! Even the 800# for LV answers with Louie Vuitton. So, just curious is all. Do you say "LV" or "Louie" or "Louis" or what?
