I think most all of the lines are classy..as for "cheap," I'd have to say the Ambre line. No matter how many times I see it, it never grows on me any more.
I love my Fringe Speedy and I absolutely hate the theda style--all those straps and buckles The Suhali line is pretty classy and I love the look of the Epi, but not the yellow one. But for me the cheapest looking one is the Cerise line. Cherries with smilie faces? Ick. Followed by the panda line. If I wanted a cute cartoon character on my purse I could dig out my old Love is stuff from the 70s
They all look classy on a classy chick! I have seen many people wearing many LV bags in my area (LA). When you look stunning, you can get away with anything!
