Elisa and
Alessia are a bit too similar. I think they are usable together if she really loves it more than anything, but if there are other names she likes too I would suggest to go with something else. They are not only similar in sound, they also both feel like their best time is behind them. Not dated yet, but not exactly fresh either.
Giulia is nice but it is so incredibly common that I would stay away from it.
Ilaria seems dated, she seems to like names that were more common a few years ago :P Same with
Serena and
Sonia! I guess
Serena and
Sonia would almost be unusual for a child born nowadays!
Virginia is nice and classic but has teasing potential,
Gabriella and
Valentina seem dated.
Martina is also starting to sound tired. I would go with
Noemi!
Noemi is wonderful.
Okay so
Noemi is the best, in my opinion.
Sonia is kind of cool because it would be nice to see this on a baby.
Giulia is nice and classic but too common.
Alessia is fine but close to
Elisa.
Still I would choose one of these, ranked in order of preference:
1
Noemi2
Giulia - ok I love the sound so much, but so common!
3
Sonia4
Alessia
these are okay:
5
Serena6
Virginia7
Ilaria8
Gabriella9
Valentina10
Martina
But none of these names are bad. They are all fine and perfectly usable!
Suggestions:
Naomi - close to
Noemi but not so common
Selena - seems fresher than
SerenaGiuliana - seems dated but less common than
GiuliaGloria - kind of similar to
GiuliaAmelia or
Amalia - same rhythm as
Alessia but less common
Matilda - kind of similar to
MartinaAlina - cross between
Alessia and
Martina :P Kind of.
