Arwen (Liv Tyler) Lord of the Rings 2001. The movie is filled with tons of beautiful costumes but the one to showcase Arwen in promotions for the films is what is called "The Blood Dress." The name is attributed to the gorgeous velvet bell sleeve. It has a red underdress with gold embroidery and a dark burgundy over dress.
The Icon of Blood is the racial crest of the blood elves, and symbolizes their fall and subsequent rise during Third War. The drop of blood represents their bretheren who fell to the Scourge, while the phoenix on the shield represents their own survival and return to power in Quel'Thalas. The golden leaves likely represent the forests of Eversong Woods.
