Everyone needs a classic cardigan — double points if it comes in a citrusy-cool hue. Channel a menswear-inspired look for the office by tucking a printed button-down into a pencil skirt, then cinching your open cardigan with a pretty floral belt. Make your neon cardi work for the weekend by throwing it over your swimsuit and a pair of striped shorts.
