In anthropological and visual culture studies, "festival symbols" refer to social expressions that convey festive meaning through specific clothing, colors, and patterns. Christmas sweaters, as an important symbol of Western traditional festivals, can be traced back to the family hand-knitting traditions of the mid-20th century.
Their exaggerated snowflake and reindeer patterns, along with their red and green color schemes, not only create an atmosphere but also carry emotional metaphors of reunion and warmth. This type of clothing has gradually moved from the family setting into the fashion context, becoming a carrier of "emotional expression" in festive social interactions.
