MANUAL Hand five spring trends according to Aimee Lippencott, eastern fashion manager for Nordstrom SHORT SKIRTS. Think a soft silhouette rather than the body-tight skirt, part of fall's '90s redux. YELLOW, IN ANY FORM. A bright yellow piece can be mixed in to give a drab outfit a pop of color. A HARDWARE HANDBAG. Instead of studded bags seen in the fall, look for more functional hardware like zippers. Bag, $75; top by Ella Moss, $95; both available at Bauhaus. THE BOYFRIEND JACKET. Buy one in the women's section or go rogue and swipe an authentic piece from a boy's closet. Blazer by La Rok, $297; dress by 12th Street by Cynthia Vincent, $138; boots by Jessica Simpson, $137; all available at Bauhaus. THE CAGED SHOE. Hold on to fall's gladiator shoe and look out for the new shoe for spring. 13 01 21 10
