Here’s the swim dress that combines everything we know and love about tunics and great-fitting swimsuits. A high neckline provides sun coverage while elongating your silhouette. The flattering tunic length, colorful piping and adjustable straps are perfect finishing touches. Underneath, of course, there’s a comfy, one-piece swimsuit. Plus, chlorine-resistant fabric keeps this swim dress in tip-top shape, season after season.
