Maxi dresses are the ultimate way to exude a stylish laid-back look. Just look at Stella McCartney's Spring '08 collection, which was filled with feminine floral maxis. Also take cue from Nicole Richie who recently frolicked LA in a paisley maxi dress. There's something to be said about a dress that can make you look put together and feel comfy at the same time. Do what you will with the neckline but make sure your maxi is floor length. After all, anything shorter wouldn't be a mile-long maxi.
