Fantherin is a store on Amazon that offers spiky, delicate, intricate and magical looking gothic fantasy headbands. Their styles include floral headband, halo style, fantasy queen and crowns.
Take a look:
I wish more of the beautiful headbands were goth-friendly silver instead of gold, but I still would love to own more than a few of these. 
Shop for these and other cosplay crowns and headpieces in the Fantherin shop!
