Trends may come and go, but in the fashion industry nothing ever really goes out of style for too long. Trend-ology focuses on a 250-year-old trend cycle—starting in the 18th century—and follows the emergence (and reemergence) of trends up into the current period. This exhibition features 100 flash-in-the-pan pieces including a tartan dress made in the early 1700s, a chunky gold Chanel necklace inspired by Salt-N-Pepa and a Murakami-designed Louis Vuitton satchel that was replicated ad nauseam. The show also touches on how trends develop and spread through various channels such as art, music and film, and how fast-fashion stores like H&M and Zara have contributed to the world of passé and beguiling trends.
