Here are some of the hottest trends from the Fall 2015 runway:
- Tie-neck Blouses. Sexy without being revealing, tie-neck blouses were huge on the fall runway. If you want to try this trend, keep the rest of your outfit relatively simple to keep it from looking too overdone. Try pairing a tie-neck blouse with a pair of jeans for a dressed-down look, or keep it work-appropriate by pairing it with a simple pencil skirt. 
- Capes. Nearly every designer had some version of a cape in their collection this year. For a casual look, try topping a turtleneck sweater and pair of jeans with a classic cape in a subdued shade of navy, gray or black. Finish it off with a pair of boots and the perfect bag to look effortlessly chic. For something a bit dressier, look for a cape in rich fabrics such as velvet or suede. Pair it with leather pants or a short skirt and boots for a fun, yet classic look. 
- Patchwork. The 70s are back in a big way, and nowhere was it more apparent than in the patchwork fabrics that dominated the autumn runway. Everything from traditional folk-inspired patchwork to more modern piecemeal designs made an appearance. If you just want to dabble in this trend, try looking for a pair of patchwork boots or a patchwork clutch. Alternatively, go all out and choose a full-length dress to really make a statement.
- Fringe. Also popular with a number of different designers, fringe is another hot trend for the fall that hearkens back to the 70s. Look for pieces that incorporate fringe accents around the edges. Skirts, coats and sweaters with fringe details are all great ways to experiment with this trend. If you want to do something a bit more wild, opt for a dress that is covered in fringe from head to toe. With tons of texture and amazing movement, a fringe dress will definitely help you stand out from the crowd.
- Victorian-Inspired Details. High necklines, ruffles, lace and other design details straight out of the Victorian area were another common thread on the runways. Look for shoes with button-up details, floral necklaces and embossed handbags to add a touch of Victorian flair to your look. If you want something a bit more dramatic, opt for a high-neck blouse with ruffles or a velvet dress with lace-patterned cutouts.
