Ava - So overused now, I prefer Eva to this even though both are very popular nowadays.
Ayla - Lovely pronounced ay la not when people pronounce it eye la (which is Isla) which people seem to do on mumsnet… I’ve known 3 Aylas in my 30 years and all have been as it is spelt.
Isla - used to love it but it’s very very overused now, same boat as Ava to me.
Nina - I’ve only ever known one Nina so it’s definitely not overdone imo and I think it’s a lovely sounding name.
Sienna - I love this, and nn sisi (cee cee)
Gia - pretty! also Gianna, Giovanna & Gianina
Mia - a bit nothingy to me.
Georgia - gorgeous name.
Luella - not keen on this
Eloisa - I prefer Louisa
Rose/a - Rose as first name is gorgeous. In the middle it’s way overdone.
Sarah - Different to the rest on your list and a bit more “retro” I guess the last influx of Sarah’s being born was in the 80s/poss early 90s. I think a little Sarah would be quite darling.
Chloe - love this too, I find it really elegant.
Gia, Sienna, Georgia & Chloe are my top ones from your list :)
