So we’re looking for a sister name for [name]Alexia[/name]. 
I suggested [name]Charlotte[/name] and he likes it. I’m just worried it’s too “Plain” in comparison to [name]Alexia[/name]. 
What do you think?
[name]Alexia[/name] is a form of [name]Alexandra[/name] and [name]Alexandra[/name] and [name]Charlotte[/name] are a good pair. I do agree that [name]Alexia[/name] sounds a little more lighter and modern than [name]Charlotte[/name] with its vintage feel. However, I do feel that [name]Charlotte[/name] is a pretty versatile name that goes well with the most unlikely choices and [name]Alexia[/name] is one of them. [name]Lexi[/name] and [name]Lottie[/name] would be a great pair of sisters. And the best thing is that you and your husband both like it so …go for it!
I love [name]Alexia[/name]! It’s very pretty 
[name]Charlotte[/name] doesn’t exactly “go” with [name]Alexia[/name] but it isn’t too far off [name]IMO[/name]
I think the nn’s [name]Lexi[/name] and [name]Lottie[/name] are cute as well.
Other names that you may like:
[name]Madeleine[/name] “Mad-uh-leen” could call her [name]Lena[/name] or [name]Maddy[/name]. [name]Lena[/name] and [name]Lexi[/name] are cute
[name]Claudia[/name]
[name]Ada[/name]
[name]Stella[/name]
[name]Josephine[/name]
[name]Vivianne[/name]
[name]Violet[/name]
[name]Ariane[/name]
[name]Scarlett[/name]
[name]Jolie[/name]
[name]Ruby[/name]
[name]Nora[/name]
[name]Greta[/name]
[name]Halle[/name]
I don’t think [name]Alexia[/name] and [name]Charlotte[/name] are great together, but they don’t clash, either. To me, [name]Alexia[/name] needs a name paired with it that has more spunk (even though I do like [name]Charlotte[/name]!)
Some other names to consider (some of these are spunky, some I just like with [name]Alexia[/name]):
[name]Phoebe[/name]
[name]Saskia[/name]
[name]Francesca[/name]
[name]Annika[/name]
[name]Kierra[/name]
[name]Clarissa[/name]
[name]Felicity[/name]
[name]Lila[/name]
Oooh, I like [name]Ariane[/name]!
