Hey! I really like these two names but i can’t pick which one.
Personally I prefer [name_f]Charlotte[/name_f]. [name_u]Courtney[/name_u] feels a bit dated, and while it is a nice name, it doesn’t have the same charm to me as [name_f]Charlotte[/name_f].
[name_u]Courtney[/name_u] may be a bit “dated”, but [name_f]Charlotte[/name_f] is becoming very popular. For that reason, I’d say [name_u]Courtney[/name_u] (but I may be a bit bias).
It also depends what style you want… [name_f]Charlotte[/name_f] is very classic, while [name_u]Courtney[/name_u] is slightly edgy (imo) and unisex.
[name_u]Courtney[/name_u]- (nn [name_f]Coco[/name_f] or [name_m]Court[/name_m])
[name_f]Charlotte[/name_f]- (nn [name_f]Char[/name_f] or [name_f]Lottie[/name_f])
I vote for the lovely and classic [name_f]Charlotte[/name_f] 
[name_f]Charlotte[/name_f] is more classic. [name_u]Courtney[/name_u] for girls is more dated. So while [name_f]Charlotte[/name_f] is very popular right now, it’s also a name that feels appropriate at any time. [name_u]Courtney[/name_u] feels indicative of a specific point in time.
[name_m]Thay[/name_m] being said, if you want a name thay’sless common right now then [name_u]Courtney[/name_u] would make sense. If your don’t mind popularity, then I definitely say [name_f]Charlotte[/name_f].
Another vote for [name_f]Charlotte[/name_f]!
[name_f]Charlotte[/name_f], despite its popularity.
I prefer [name_f]Charlotte[/name_f], more feminine but not too frilly. Good luck deciding!
[name_f]Charlotte[/name_f] for me! [name_u]Courtney[/name_u] is a fine name; [name_f]Charlotte[/name_f]'s just one of my favorites haha. I think it’s so pretty, and love its nicknames! Especially [name_f]Lola[/name_f] and [name_f]Lottie[/name_f], but [name_f]Char[/name_f] or even [name_u]Charlie[/name_u] are nice, too.
I do love the idea of [name_f]Coco[/name_f] for [name_u]Courtney[/name_u], though, if you go that route!
I’d personally pick [name_f]Charlotte[/name_f] despite popularity! [name_u]Charlie[/name_u] and [name_f]Lotte[/name_f] are such cute nicknames. I love the suggestion of [name_f]Coco[/name_f] for [name_u]Courtney[/name_u], though, and there’s nothing wrong with [name_u]Courtney[/name_u], I just find [name_f]Charlotte[/name_f] more appealing.
[name_m]Even[/name_m] though it’s quite popular right now, my pick is decisively for [name_f]Charlotte[/name_f]. It’s classic, polished, and elegant.
