? [name]Serafina[/name] and [name]Olivia[/name] - [name]Love[/name] them even though they don’t 100% match.
? [name]Indigo[/name] and Fucshia - No. [name]Don[/name]'t like the names to begin with, but it makes it even worse that they’re both colors.
? [name]Tiziana[/name] and [name]Oriana[/name] - Too matchy and I just don’t like them.
? [name]Lila[/name] and [name]Mia[/name] - I think these are super cute and adorable. A little matchy but I love them.
? [name]Sienna[/name] and [name]Pia[/name] - Not a fan of [name]Pia[/name] at all. I like [name]Sienna[/name]
?Zhara and [name]Calla[/name] - [name]How[/name] about [name]Zahara[/name]? I love [name]Calla[/name]! Good combo.
?[name]Phoebe[/name] and [name]Miranda[/name] - [name]Don[/name]'t completely love [name]Pheobe[/name] and [name]Miranda[/name] is a tad dated to me but the names are not bad. I like it.
?[name]Morena[/name] and [name]Aitana[/name] - [name]Don[/name]'t like [name]Aitana[/name]. [name]Morena[/name] is pretty cute though
?[name]Serafina[/name] and [name]Josefina[/name] - [name]Way[/name] too matchy, but I [name]LOVE[/name] them both on their own.
I would try mixing [name]Serafina[/name], [name]Olivia[/name], [name]Lila[/name], [name]Mia[/name], [name]Sienna[/name], Zhara, [name]Calla[/name], [name]Phoebe[/name], [name]Miranda[/name], [name]Morena[/name], and [name]Josephina[/name] for some new combos but I think you do have some solid combos.
I like [name]Sienna[/name] and [name]Olivia[/name] the best together!

These work well:
[name]Lila[/name] and [name]Mia[/name]
[name]Sienna[/name] and [name]Pia[/name]
Zhara and [name]Calla[/name]-- [name]Zara[/name] (this spelling) and [name]Calla[/name] would be lovely! 
[name]Phoebe[/name] and [name]Miranda[/name]
These don’t work as well:
[name]Serafina[/name] and [name]Olivia[/name]-- Since [name]Olivia[/name] is #3 and [name]Serafina[/name] isn’t even ranked in the Top 1000 (US), the two are a bit mismatched.
[name]Indigo[/name] and Fucshia-- I like them both, but they have too much color.
[name]Tiziana[/name] and [name]Oriana[/name]-- [name]Both[/name] names end in -iana, so they’re a bit too matchy…
[name]Morena[/name] and [name]Aitana[/name]-- I’m not a huge fan of either name…
[name]Serafina[/name] and [name]Josefina[/name]-- [name]Both[/name] names end in -fina, so they’re too matchy for me…
I’ll vote for [name]Phoebe[/name] and [name]Miranda[/name].
I voted [name]Serafina[/name] & [name]Josefina[/name] b/c they have cute short versions ([name]Sarah[/name] and [name]Josie[/name]) and long elegant versions.
