Yes they are, they need more cosplay love!
Hmm... I definitely think Isane now. xD And Unohana, Nanao and possible also Miyako Shiba. Maybe you could also do Neliel (adult) and Cyan Sung-Sun if you'd like some arrancars.
Do you care about crossplaying? Otherwise maybe I could suggest some male characters too.
Thank you, I'm always glad to help!
And you look so cute with that wig on!
