With a new year brings trends that we're ready to welcome into the fold and others that can see themselves out. But which is which? Read on for insider info from the pros at Saks Fifth Avenue, Bloomingdale's, The Shoebox, and other major retailers, reports ELLE.

IN: "Stripes are the equivalent to what a white t-shirt used to be back in the day," says Roopal Patel, fashion director of Saks Fifth Avenue. "They have nine lives. We've seen the trend now for two to three seasons and it will continue to carry forward."

IN: "Sneakers will continue to be extremely popular in the upcoming year," advises Gennie Yi, Intermix's buyer of designer and ready-to-wear. "Because of their versatility, you can never have too many. Glitter, leopard, and satin updates to sneakers effortlessly dress up an outfit and give you a reason to buy multiple pairs."

IN: "There was an artistically inspired theme across the runways," says Kate Foley, contributing fashion director of Vestiaire Collective. "From Roksanda and Céline to J.W.Anderson, Proenza Schouler, Marni, Valentino, and many other brands, whether directly inspired by a particular artist's work, painterly prints, or patterns, strong art references will be here to stay in 2017."

IN: "There is a new attitude shift toward 'easy elegance' going into spring 2017," says Brooke Jaffe, Bloomingdale's OVP and fashion director of ready-to-wear. "The influence of athletic-inspired pieces will continue."

IN: "One shoe trend we see really taking over in 2017 is the mule," says Sean Kirschenbaum co-owner of The Shoebox. "Flat mules, low block-heel mules, heeled mules, sneaker mules, espadrille mules—mules in all fabrications and colors including velvet, satin, canvas, and embroidery. They were big for 2016 and they will be even bigger for 2017."
