My favorites are: [name_f]Lillian[/name_f] & [name_f]Louise[/name_f], [name_f]Eleanor[/name_f] & [name_f]Emilia[/name_f], [name_f]Delia[/name_f] & [name_f]Daphne[/name_f], [name_f]Lenore[/name_f] & [name_f]Lydia[/name_f] and [name_f]Harriet[/name_f] & [name_f]Hazel[/name_f].
I think the names [name_f]Ada[/name_f] & [name_f]Abigail[/name_f], [name_f]Sylvie[/name_f] & [name_f]Stella[/name_f] and [name_f]Bonnie[/name_f] & [name_f]Beatrix[/name_f] “[name_f]Bea[/name_f]” have different styles, in my opinion. [name_f]Willa[/name_f] & [name_f]Winnie[/name_f] are too similar for me.
I like [name_f]Ada[/name_f] & [name_f]Abigail[/name_f] (nn [name_u]Abby[/name_u])
[name_f]Sylvie[/name_f] and [name_f]Stella[/name_f] also sound cute together!
[name_f]Lillian[/name_f] and [name_f]Louise[/name_f] is my favorite-- both classic names and [name_f]Lily[/name_f] and [name_u]Lou[/name_u] are cute nns too!
I believe, for twins, if beginning with the same initial, the remainder of the names should sound very different from one another.
[name_f]Stella[/name_f] & [name_f]Sylvie[/name_f] is my favourite – the two work together so well, and I like the mix of zest and sweetness of them both. To make my top three of this list, I’d add [name_f]Harriet[/name_f] & [name_f]Hazel[/name_f] and [name_f]Eleanor[/name_f] & [name_f]Emilia[/name_f].
The two I do find too similar on your list for twins are [name_f]Willa[/name_f] & [name_f]Winnie[/name_f] and [name_f]Molly[/name_f] & [name_f]Mae[/name_f].
[name_f]Stella[/name_f] and [name_f]Sylvie[/name_f]! Also really like [name_f]Lillian[/name_f] and [name_f]Louise[/name_f] and [name_f]Lenore[/name_f] and [name_f]Lydia[/name_f].
[name_f]Bonnie[/name_f] & [name_f]Beatrix[/name_f] is my favorite. I would also love [name_f]Lillian[/name_f] & [name_f]Louisa[/name_f] or [name_f]Hattie[/name_f] & [name_f]Hazel[/name_f]
Top 3 for me:
[name_f]Eleanor[/name_f] and [name_f]Emilia[/name_f]
[name_f]Ada[/name_f] and [name_f]Abigail[/name_f]
[name_f]Delia[/name_f] and [name_f]Daphne[/name_f]
My top 3, in no particular order, are [name_f]Sylvie[/name_f] and [name_f]Stella[/name_f], [name_f]Bonnie[/name_f] and [name_f]Beatrix[/name_f], and Harrier and [name_f]Hazel[/name_f]
