“Darkness 1.0” is a tube top dress, which is based on two classic men’s trousers. Through 3D draping, the trousers are dissected and assembled into a tube top dress. The upper body of the dress is a tube top with a suit pants double-waisted structure, and the lower body is an A-line skirt with ruffles on both sides of the skirt and a pleated design on the back.
