Oscar is one of my favourite names ever. I don't think I can use it, but due to association boy do I love it. I also like
Oz as a nickname, and depending on my mood, even
Ozzie /
Ozzy can work (because
Ozzy Osbourne sometimes lives in my head uninvited for some reason).
I also really like:
Ocean...
Océane is so much more effortlessly cool though.
October... every over-grown goth's favourite month, ofc.
OlwenOpaline... prefer
Opal. It's more...it is what it is... it owns itself and it's neat.
OssianOttilie...lovely, also really like
Ottoline, which is more clunky-chic.
Other O names I personally love:
OctaviaOlympiaOonaOrphéa
OisínOzias
