[Opinions] I really like it.
That happens to me, too, by the way. I may despise a name for odd reasons, but if I meet someone I like with the name, it grows on me considerably. Some of those names end up being favorites.
Anyways, back to Bianca, it's one of my favorites, though I would probably never use it myself (something seems odd about using somewhat obviously Italian name when I don't believe I have a drop of Italian blood in me). Well, actually, I wouldn't use it for a first name, but it's the middle name in one of my favorite combos (Rose Bianca).
Though, the name does have a vaguely "trashy" (I hate using that word, but I can't think of anything else at the moment to convey the same image) air about it. But I think that can be overcome. And I still love it.
