Style Tale: Persephone
You don't need to belong to another world to be otherworldly. Just take a leaf from Persephone's wreath. Add crown jewels and metallics to an otherwise black and white palette and you will glow. And remember, if forced to choose between dark and light, find the silver lining.
But actually, I think it's humanly impossible to feel human when wearing fairy crowns or face jewels. They make you feel far too ethereal. If fake it till you make it is true, and I think it may be, maybe one day you'll wake up magic. So there's that.
