Polka dots perfectly express your timeless (but fun!) style. Sure, they're a little retro, but they're also very hot and one of spring's best trends. Right now, you can find them on everything from basic belts to formal dresses. Besides traditional all-white or all-black dots on a solid fabric, look for patterns featuring dots of several different colors. This graphic design is cute, cheerful, and also classic! Another trend to try: Floral.
