Soft, stretchy, and summery, this flirty day dress is ready for vacation. A keyhole opening at the back adds a cute touch, with a tie detail and elastic trim that keeps the fabric from drooping—and prevents your bra band peeking out. Cinch the ties or leave them looser to adjust the opening as you wish. A rounded neckline and two side-seam pockets complete the look. In cooler weather this dress is just as sweet with leggings and a cropped cardigan.
