This tank dress is as easy as it gets—and it’s also incredibly flattering. It has a high round neck, a racerback, and a deep scoop at the arm. The cut is straight, skimming the body just so with a gentle curve in at the waist. Done in a midweight, softly structured cotton with a center seam in front and back, it falls to an ankle-length hem and is finished with a discreet side zipper.
