[name_f]Piper[/name_f] and [name_f]Suvi[/name_f] is my favorite of the sets! I just love how warm and summery and fun they feel together. They’re lively and youthful but still stylish and sleek 
[name_f]Clementine[/name_f] and [name_f]Agnes[/name_f] are a close second.
If I were to rearrange or change them, I’d probably give [name_m]Ziggy[/name_m] a longer full name because the nickname-y, unisex [name_m]Ziggy[/name_m] feels mismatched to me with the longer, feminine, elegant [name_f]Callista[/name_f]. Something like [name_f]Sigrid[/name_f] and [name_f]Callista[/name_f] “Ziggy and Cal” or [name_f]Elizabet[/name_f] and [name_f]Callista[/name_f] “Ziggy and Cal” would make more sense to me. [name_m]Or[/name_m], I would swap the sister pairs to be [name_m]Ziggy[/name_m] & [name_f]Merritt[/name_f], and [name_f]Winifred[/name_f] & [name_f]Calista[/name_f]. While I don’t think [name_f]Winifred[/name_f] and [name_f]Merritt[/name_f] clash badly, I do find them very different styles: the old-fashioned, heavier [name_f]Winifred[/name_f] versus the unisex, surname-y [name_f]Merritt[/name_f]. Plus, in the sibset of [name_f]Winnie[/name_f] and [name_m]Rhett[/name_m], I would definitely assume [name_m]Rhett[/name_m] was a brother, even if it’s a cool nickname for a girl (sisters [name_m]Ziggy[/name_m] and [name_m]Rhett[/name_m] would make more sense to me!).
What full name ideas would you suggest for [name_f]Minnie[/name_f], besides [name_f]Minerva[/name_f]?
