Fall Fashion Trends. Our 2018 guide to spring fashion has all the best style trends, hottest clothing items, and latest runway collections. These are the biggest fall fashion trends that will dominate menswear and womenswear this year from crystal fringe to ’80s silhouettes. From a huge 1980s fashion revival (think big shoulders and black leather) to futuristic metallics and menswear-inspired jackets, these are the fall trends to keep on your radar. Classic Saville Row fabrics like herringbone, glen plaid, and houndstooth look richer than ever.
