[name_f]Dorothy[/name_f] is one of my all-time favs! So pretty and classic. [name_m]Olivier[/name_m] is a great and handsome choice, however it most likely will be confused for [name_m]Oliver[/name_m] a lot. That wouldn’t be a dealbreaker for me, but if that would bother you I wouldn’t use it. If it doesn’t bother you, go for it!
