I personally think [name_f]Lydia[/name_f] is a little fancy and I would consider [name_f]Vivienne[/name_f] and [name_f]Evangeline[/name_f] at a similar level of fancy - especially if you are ok with using nicknames! My taste tends to run to fancy so these may be a little much but here are my best guesses
[name_f]Sylvia[/name_f]
[name_f]Gloria[/name_f]
[name_f]Imogen[/name_f]
[name_f]Laurel[/name_f]
Juliet/Juliette
[name_f]Miranda[/name_f]
[name_f]Dorothy[/name_f]
