I like it a lot more than
Sebastian. I think it is very regal and elegant- a beautiful deep red. It is too frilly for my tastes but I'd like to see it on someone else's child. What would you use for a nn? It is too long to go without one.
Tia would be quite cute. Or Basti.
Sebastiana June Frances would be my first pick. Second would be
Sebastiana Eve Beatrice.
