A few weeks ago, I got a head start on spring break—a dress rehearsal, if you will—down in Miami. My starring costume? The breeziest, button-down dress, above, which racked up more compliments than a puppy on a long leash. When I got back, I passed it to my twin sister, who whisked it off to Puerto Rico and now Palm Beach. At this point, the dress is having a longer, more luxurious spring break than either of us—I'm just waiting for it to start sending postcards! (See more of its adventures on my !)
