Vanessa, followed closely by
Veronica. I like the way it sounds. Very soft and beautiful.
Veronica is beautiful as well but in its own sort of way.
I don't care for
Valerie at all. It neither looks nor sounds pleasant. Also, the ones I've known with this name I have not cared for-and for good reasons, especially this one in paticular. I'd feel hesitant if I were to meet another one.
