With the above title, what name comes first to your mind?
[name_f]Eve[/name_f]
[name_f]Liv[/name_f]
[name_f]Elle[/name_f]
I agree with @fireweed25 about [name_f]Elle[/name_f], [name_f]Liv[/name_f] and [name_f]Eve[/name_f].
Also adding (by short I think about 1-2 syllables):
[name_f]Luna[/name_f]
[name_f]Esme[/name_f]
[name_f]Lea[/name_f]
[name_f]Fleur[/name_f]
[name_f]Liesl[/name_f]
[name_f]Rosie[/name_f]
^^^ I cast a third vote for [name_f]Liv[/name_f].

[name_f]Jade[/name_f]
[name_f]Lucy[/name_f]
[name_u]Blair[/name_u]
[name_f]Kate[/name_f]
[name_f]Lux[/name_f]
[name_u]Shay[/name_u]/[name_u]Shae[/name_u]
[name_u]Pax[/name_u] and [name_f]Jinx[/name_f] came to mind.
The first name that comes to mind is [name_f]Jade[/name_f]. I’ve always thought of it as effortlessly cool.

Looks like [name_f]Liv[/name_f] is the most effortlessly cool at least it is the one that has been mentioned the most. She’s cool but familiar enough that she’s not trying too hard.
