This blue-and-white floral dress was one of several Johanna Ortiz pieces Sarah bought from the same collection. Made from airy broderie anglaise cotton, it has a sweetheart neckline framed by voluminous puff sleeves, a fitted bodice, and a flowing tiered midi skirt. “There were three or four dresses from that collection that I picked up and wore religiously,” Sarah says. “They fit me so well, and they’re completely in line with the Palm Beach sensibility.” This one traveled beyond Florida, too: Sarah remembers wearing it to a dinner at a friend’s ranch outside Aspen.
