A single mediocre artistic expression no longer meets people's pursuit of art. Various artistic fusions of the collision of sparks are now required to meet people's emotional expression. Objective: To produce innovative design concepts, design methods, and styles by integrating different art disciplines. This paper takes architecture and clothing as the main research contents. It analyzes the external and internal correlation between architecture and clothing from the characteristics and architecture’s development as the starting point. It analyzes the intersection between architecture’s design language and apparel. It summarizes the design methods based on the apparel design perspective. Methods: Adopting the literature research, case study, and literature picture analysis methods, we summarize the relationship between architecture and clothing. This research conducted an in-depth and accurate interpretation of the design application method. It combined theories and brand show analysis inspired by architecture. Results: Based on the diversity of architectural style characteristics in the context of different periods of time for clothing design to open up more ideas, coupled with the development and support of modern technology fabrics, the development of the clothing industry has a certain role in promoting. Conclusion: The mingling and reproduction of various artistic expressions are due to designers' multi-dimensional exploration in cross-cutting fields. Therefore, the development trend of design art is the cross-border integration of multiple fields. Integrating architecture and clothing provides a new design space and orientation for the innovation and development of clothing design and opens up artistic design thinking.
