I used to prefer
Vivien, but now I like
Vivienne. It's very soft. I do like
Vivian too, but I agree it's not as feminine. I don't particularly like it on a male, but it does have a strong darkness about it. I also find that
Vivien kind of bothers me because I get confused feelings when looking at it-- it's a mix of
Vivian and
Vivienne.
