I don't find it ugly (but then, my standards are questionable), it's imposing for sure. It makes me think of... voluminous. Which is a very satisfying word. I think I prefer
Fulvia to
Flavia, which I can't quite get into.
I like
Fulvia Isidora quite a lot. I really want to pair
Fulvia with a name that has that long, dramatic "or" in it, like...
Fulvia Eléonore.
