Concept art: Mourning dress for Cersei Lannister

An idea for a dress never shown in the series, mixing up the visual style designed by Michele Clapton for Game of Thrones and George R. R. Martin's description in the book:
"The queen wore a high-collared black silk gown, with a hundred dark red rubies sewn into her bodice, covering her from neck to bosom. They were cut in the shape of teardrops, as if the queen were weeping blood. Cersei smiled to see her, and Sansa thought it was the sweetest and saddest smile she had ever seen." (From "A Game of Thrones")
