Gucci GUC red-and-green Web wool-blend suit trousers. Made from custom-woven Yaoyan Zhenxu fine worsted wool. The Web stripe is inserted into the center of the trouser side seam using a concealed piped seam, leaving the stitching hidden and the surface flat without bulk. The source states that this construction helps prevent the stripe from curling or detaching during extended wear and requires precise sewing alignment. The stripes on the left and right legs are aligned. Ergonomic three-dimensional pattern cutting uses careful paneling, folding, gathering and stretching to shape the garment. The process is described as intricate and time- and material-intensive, with attention to fabric texture, fit and wearing comfort. Relaxed fit.
