honestly I prefer natural asterion but if you need outfits. I prefer outfits that reveal the body completely except the crotch. while searching on twitter i found some examples (which comes from hades game fanart) 
Or this is good too
and i would love to see asterion with the same cape as on the art of @GigaSaddle
I hope to have given you some ideas .
in any case good continuation and I am really looking forward to tomorrow to play the new update.
