Very pretty. I think I still prefer Vivien, but if you want something a little frillier, Viviette fits the bill. The crispness of the first syllable keeps it from being too terribly saccharine.
Thank you-my other daughter's name is frilly, I guess its my style. We like Vivienne but its getting very popular. We chose a popular name for my son, unknowingly, so we are more aware now! I like Juliette but also popular. Thanks for your opinion!
