[name_f]Margot[/name_f] is elegant and glamorous!

[name_f]Amelie[/name_f]
I think all 3 names are beautiful. My favourite would be [name_f]Claire[/name_f], then [name_f]Alexandra[/name_f] then [name_f]Margot[/name_f].
I also think combos of these 3 names would be beautiful
[name_f]Claire[/name_f] [name_f]Alexandra[/name_f]
[name_f]Margot[/name_f] [name_f]Alexandra[/name_f]
[name_f]Claire[/name_f] [name_f]Margot[/name_f]
[name_f]Alexandra[/name_f] [name_f]Margot[/name_f]
[name_f]Margot[/name_f] [name_f]Claire[/name_f]
[name_f]Alexandra[/name_f] [name_f]Claire[/name_f]
(Any would work these names are solid, timeless and beautiful)
What I would say is if you go with [name_f]Alexandra[/name_f], you need to think of a nickname that you like, and introduce her to people with that name. Otherwise everyone will shorten it to [name_u]Alex[/name_u]. If that isfine, then it’s fine, but if you her nickname to be [name_u]Lexie[/name_u] or something, then you need to tell people that when she is introduced.
(My name is [name_f]Alixandra[/name_f] by the way 
That’s why I’m saying about the nicknames)
I love [name_f]Alexandra[/name_f]. I think [name_f]Alexandra[/name_f] [name_f]Claire[/name_f] is a gorgeous combo. My favorite nns for [name_f]Alexandra[/name_f] are [name_u]Alex[/name_u] and [name_u]Sasha[/name_u].
All of your names have a vibe that I’d call “classic tailored feminine.” Familiar but not trendy, beautiful but not too frilly. Other names that hit this vibe for me are:
[name_f]Audrey[/name_f]
[name_f]Josephine[/name_f]
[name_u]June[/name_u]
[name_f]Louise[/name_f]
[name_u]Simone[/name_u]
[name_f]Maeve[/name_f]
Definitely [name_f]Margot[/name_f]!
Another vote for [name_f]Margot[/name_f]. Both [name_f]Claire[/name_f] and [name_f]Alexandra[/name_f] are great with it as middle names. I’d pick whichever flows better with your surname.
[name_f]Margot[/name_f] is my favorite of your options, but it seems like you have found your style–classic, elegant, and strong–so I think you are likely to be happy with whichever you choose.
I love all your options. Other names that may fit your style:
[name_f]Eve[/name_f]
[name_f]Audrey[/name_f]
[name_f]Jane[/name_f]
I like [name_f]Alexandra[/name_f] out of those.
