There are too many fish in the sea, but this Halloween you can stand out as ruler of the ocean. The Men's King Neptune Costume includes a robe with cape, chestplate, cuffs, crown and rope to hold the cape in place. The robe is light blue, just like the color of the sea. The brown chestplate features decorative accents that give the appearance of muscles. At the bottom of the chestplate are layers made to look like the tassets from armor. In Roman mythology, Neptune is the sea god and brother of Jupiter, King of the Gods. He is also known by his Greek name, Poseidon. Beard, trident and sandals are not included.
