Hello Felie,
I like
Olympia and
Ophelia (these spellings). I also like
Océane.
Olive is okay, but I don't like
Olivia.
Oliva sounds like it's missing something. Oliveiro/a sound too much like soap.
Odilia is kind of cute. The others are not my style. I think
Odilia could become popular if some celebrity used it because it is close to
Olivia and
Lydia and
Ottilie but it sounds better.
Please rate my list:
