Hello...
First time tpf poster here!
I recently made my first (& second) Vuitton purchases. I was deciding between the Neverfull & the Batignolles Vertical. I decided to go with the Batignolles, and I couldn't be happier. The bag has more structure than the Neverfull, and has a great professional look. Although there are some differences in shape between the Batignolles Horizontal and Veritcal, I think both bags give off the same classy image.
Of course once I made my purchase I was hooked, and a week later had to buy the new, bigger Vernis Cles in Pomme.
Good luck deciding, and remember, you can never have too many bags!
