Although I’ve only heard it for boys, I think a [name_m]Pierre[/name_m] would be really cute for a little girl 
[name_m]Pierre[/name_m] doesn’t work for a girl in my opinion. It’s such a well know french boys name there’s no getting away grom that.
I especially love the girl’s name [name_f]Pia[/name_f] pronounced Pier. A beautiful refreshing take on [name_f]Mia[/name_f] and [name_f]Tia[/name_f].

I would have to say no, sorry. [name_m]How[/name_m] about [name_f]Petronella[/name_f]? I know a girl with this name, and it’s absolutely stunning.
[name_f]Pia[/name_f], [name_f]Petra[/name_f], [name_f]Petronella[/name_f] or [name_f]Pietra[/name_f]. Not [name_m]Pierre[/name_m].
I can’t get behind [name_m]Pierre[/name_m] as a girl’s name, sorry.
Many of the other suggestions being floated around are quite nice
