Inspired by 1950’s college button-up sweaters, this light blue cardigan from UK brand Collectif will earn you major points toward your retro-chic style game! Made from a soft knit fabric, this stylish cardigan boasts vertically slanted rainbow stripes at the front that converge into a V-shape in creamy shades of violet, lavender, blush pink, and deep pink, a complimenting V-neckline, long sleeves, and button-up closure.
