Polka-dot prints generally evoke a playful quality that's both retro-inspired (think Sandra Dee as Gidget) and youthful. And while that's certainly still the case with Taylor Swift, we can't help but notice that the singer has put an undeniably sophisticated spin on the look. If you're thinking her classic strand of pearls is behind the enhanced grown-up appeal, you're right and on the right track. See, it's more than just her timeless jewelry statement that has us convinced. Taylor smartly styled the quirky black and white, cat-embroidered French Connection sweater with fitted burgundy-hued ankle-cut trousers, a pairing that proved more serious in tone and execution. To finish, she opted for a structured bow-tie ballet flat that, while girlie, actually rounded out her ensemble on a sleek, feminine note. As the record shows, polka dots are no longer a print meant purely for Summer rompers and cute bikinis, it's a print for all seasons with a lot of polished promise. We've picked our favorites to shop below, and each sweater — topped off with the proper outerwear — is fit to be worn now.
