I have liked
Dora since I was little and it was the name of the street my grandparents lived on.
I think it is old fashioned and sweet. I said the same thing about
Lucy but it is cute without being cutesy. I can picture a young
Dora or an old
Dora. I like it as a nickname or on it's own.
I do think of
Dora the Explorer but it is not the first image that pops into my mind.
