I love
Vivian! I used to be pretty neutral on it but lately it has really been growing on me. I definitely prefer
Vivian over the other spellings but I prefer less frilly names in general.
Vivienne would be the only other spelling I would consider.
Vivien makes me think "vixen" for some reason.
Vivianne just doesn't look right to me and makes the name seem/look trendy.
I haven't really though of many combos with
Vivian yet as it is new to my list and pretty far down on it still.
My first though was
Vivian Elise (although I don't particularly care for
Elise) or
Vivian Estelle, maybe?
