I distinguish between beautiful and pretty, and possibly my ideal name would be somewhere inbetween beautiful and pretty with a bit of strength thrown in too!? does that make sense!?
But beautiful names... Juliet, Annabel, Emily, Marianne, Eleanor, Lydia, Flora.
Pretty names. Zoe, Ruby, Rosie, Poppy, Libby, Eva, Evie, Sophie, Sylvie.
A perfect name (for me, very personal of course) would be something like Vivien though. Not pretty, almost beautiful but too strong to be beautiful. Beatrice is another.
