Avant-garde fashion is experimental and boundary-pushing, challenging conventional design through unconventional silhouettes and materials. Its roots are in early 20th-century art movements, and designers like Comme des Garçons and Yohji Yamamoto carry it forward. Deconstructed garments and asymmetrical silhouettes are the constants. Architectural shapes and oversized forms distort the body. Unexpected fabric combinations and unconventional footwear complete the approach.
