I love these names , in no certain order ----
[name]Claire[/name] [name]Juliet[/name]
[name]Clara[/name] [name]Juliet[/name]
[name]Stella[/name] [name]Juliet[/name]
[name]Sylvie[/name] [name]Juliet[/name]
[name]Harper[/name] [name]Juliet[/name]
[name]Elizabeth[/name] [name]Juliet[/name]
which do you prefer, if any, and why… thanks for any input:-)
1 [name]Stella[/name] [name]Juliet[/name] - spunky, vintage and classic combo! I like the way the two names and look together.
2 [name]Clara[/name] [name]Juliet[/name] - Two pretty classic names
3 [name]Sylvie[/name] [name]Juliet[/name] - A combo that has a chic French vibe.
[name]Clara[/name] [name]Juliet[/name], then [name]Sylvie[/name] [name]Juliet[/name]. All the other names are nice, I just don’t love them with [name]Juliet[/name]. [name]Sylvie[/name], [name]Harper[/name], and [name]Elizabeth[/name] are probably my favorites, name-wise, but [name]Clara[/name] [name]Juliet[/name]'s by far my favorite combo. 
[name]Claire[/name] [name]Juliet[/name] seems like perfection to me honestly!
I really prefer [name]Elizabeth[/name] [name]Juliet[/name] of your choices. I know some may say that it is too “common” perhaps, but I love the classic feel, plus [name]Elizabeth[/name] has hordes of fantastic nicknames to go with. If I had to choose another… probably [name]Stella[/name] [name]Juliet[/name]. I like how spunky it is. [name]Harper[/name] is too trendy for my taste, and I have never liked [name]Claire[/name]/[name]Clara[/name] (they just rub me the wrong way…). [name]Sylvie[/name] is alright, but the combo doesn’t wow me at all.
[name]Claire[/name] [name]Juliet[/name] is super pretty, but it makes me think of [name]Claire[/name] Danes in [name]Romeo[/name] + [name]Juliet[/name] (I was 13 at that time)
[name]Harper[/name] [name]Juliet[/name] is very beautiful, probably my favourite. They are all nice though!
[name]Clara[/name] [name]Juliet[/name] is 
[name]Clara[/name] [name]Juliet[/name] is my all time favorite combo so I love that but [name]Stella[/name] [name]Juliet[/name] is also gorgeous
I love [name]Clara[/name], [name]Sylvie[/name], [name]Harper[/name] and [name]Elizabeth[/name]! And I adore [name]Juliet[/name]
[name]Claire[/name] is just a bit boring and plain sounding to me, and I hate [name]Stella[/name], it has a harsh trashy image to me (a UK thing I’ve discovered lol).
Of the four choices I like, I’d rule out [name]Harper[/name] for it’s trendiness and the fact it will forever be tied to this particular era and will most likely become dated sounding. For this reasons I prefer it as a middle name. I really love [name]Clara[/name], [name]Sylvie[/name] and [name]Elizabeth[/name]. [name]Elizabeth[/name] is the most classic and timeless, [name]Sylvie[/name] is cute, French and adorable sounding which are qualities I love, but [name]Clara[/name] has to be my fave. Elegant and sophisticated, with vintage charm, I love it!
So my faves in order are:
Good luck!
