Though known for his ultra-feminine silhouettes, Dior adapted many aspects of menswear for his designs. He appropriated gray-flannel tailoring, houndstooth, white cotton piqué, and other elements of menswear. One of Dior's great achievements was to create from the vocabulary of men's tuxedos. Here, a black wool column is accented with black silk faille that would be in a man's tuxedo lapel and cummerbund. Visible in the asymmetrical wrapping of the pattern pieces is his interest in the drape of fabric.
