Abstract: Qiang's dress culture, which shows a kind of special aesthetic sentiment and aesthetic taste, is an exotic flower of the Chinese national dress culture. Qiang, even as the grandfather of many nationalities, is one of ancient nations, so its design, pattern and color of costumes contain deep culture connotation. The pattern design of Qiang costume comes from worshiping religion, taking up productive labor and participating in entertainment activities, which form today's Qiang dress culture and reflect its stability, specificity, nationality and personalized aesthetic connotation. This paper, on the basis of a simple conclusion of Qiang's dress in different areas, analyses the religious thoughts and its historical origin, which are reflected from Qiang dress patterns.
