We think this dress—with flattering cutouts at the side—would be absolutely perfect for anything on your agenda that calls for more festive, formal or cocktail-y attire. It features eye-catching floral fabric from Liberty (the British print house known for its mood-lifting blooms since 1875) and a cool knotted front. Plus, it's made with organic cotton that is grown without chemical fertilizers and pesticides from nongenetically modified seeds. Worn once, like new.
