This Renaissance-style headpiece titled "Autumnal Queen" is available for purchase in my Etsy shop LalaithLoot.
General info for all headpieces: One-size-fits-all headband with 2, 20" ribbons for a tighter fastening to the head. The piece is listed for $20 (US), plus shipping. As of right now, I'm not planning to do shipping outside of the United States, but if I get foreign interest, I will certainly consider opening it up.
