As a nick, Torrie / Tory / Torie /
Tori can be spelled any way at all. It doesn't necessarily have to be true to
VicTORIa. Overall, I prefer
Tori.
BTW, my
Victoria (who goes by her mn
Brooke) would have been called
Tori. She told me a few years ago that as she has gotten older she wouldn't have wanted that any longer because it's so girlish (ending 'ie' sound). Rather, she would have preferred
Toria or
Tora. I've only heard of one
Toria (local tv reporter) and would actually like to see that more often.
