Celebrity stylesetters are readying for the resorts in sidewalk-sweeping dresses. "I love seeing a maxidress worn in a casual way," says designer Corey Lynn Calter, who designed mother-to-be Jessica Alba's dress. "Keeping it simple makes this style very modern." Angelina Jolie picked up several Gerard Darel dresses for her own pregnancy. "The maxidress is an effortless piece, and Angelina has worn all our dresses with a natural ease," Darel says. "I feel that the dress accentuates her femininity." Non-expectant fashionistas can also flaunt their feminine figures in the easy style. Just add bejeweled sandals for extra Bohemian chic.
