Santa Claus
Santa Claus, also known as Saint Nicholas, Kris Kringle, Father Christmas, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December). The modern Santa Claus grew out of traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas and the Dutch figure of "Sinterklaas" (himself also based on Saint Nicholas). Some maintain Santa Claus also absorbed elements of the Germanic god Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky.
Santa suit
A Santa suit is a costume worn by a person portraying Santa Claus. The modern American version of the suit can be attributed to the work of Thomas Nast for "Harper's Weekly" magazine, although it is often incorrectly thought that Haddon Sundblom designed the suit in his advertising work for The Coca-Cola Company. Sundblom's work did standardize the western image of Santa, and popularized the image of the red suit with white fur trim. This has become the image of the American Santa, while in some European countries where Saint Nicholas remains popular, the outfit worn is closer to religious clothing, including a Bishop's mitre.
