Get spotted this season in one retro trend that is making a splash all over the spring runways. Polka dots are back but not as kitschy as your mom’s ’80s skirt or silk chiffon dress. Michael Kors, ADAM and Betsey Johnson, the mistress of all things whimsy showed polka-dot frocks, and separates in their spring collection. What I adore about the trend it’s fresh, classic and adds just the right punch without going overboard. Every piece I saw on the runway is wearable and flattering.
