Resort collections are the epicenter of a sea change overtaking the fashion industry. What The New York Times declared in 1989 “the most mysteriously labeled of all fashion seasons” has morphed into the look of our times: trans-seasonal clothes for an age of global warming and a population shift to states with warmer climates. L. Boutique presages the trend with the debut of a new resort department devoted to lightweight dressing and sunny vacation-inspired clothes, like Trina Turk’s exotic floral maxi dress with keyhole halter top ($328). L. Boutique, 556 S. Pineapple Ave., (941) 906-1350.
