I love this look from Jean Paul Gaultier's Fall 2015 Couture collection! I think it would make a killer villainess or femme fatale look (no pun intended?)
… Actually my first thought when I saw this look was of Bloodborne. I immediately thought of the Mensis Cage when I saw the headdress, but this whole outfit seems like it would fit right into the game. The actual inspiration for the various beautiful headdresses in the collection are traditional coiffes from Brittany, which are worth a quick image search.
