Very
Demi Lovato. I like the name
Demetria a lot and
Demi is a cute NN, but I would probably just call a
Demetria by her full name. I think it's so pretty by itself. It's totally usable, I don't think it's been ruined, nor do I think it is too odd. Especially considering that
Dmitri and its variants are not unheard of where I live.
