As high winds buffeted the tent outside the Chicago History Museum—where the runway show “Dress Code” was held Wednesday night—causing the fabric walls to ripple and lighting rigs to sway, I couldn’t help but wonder how the headlines would read if everything were to collapse onto the assembled audience of fashion students, instructors, journalists, models, and designers. “Local fashion industry decimated” sounded good, if a bit dramatic. But this show—devoted to the work of students at the International Academy of Design & Technology, the School of the Art Institute of Chicago, Columbia College, and the Illinois Institute of Art—is all about drama. As students, the designers don’t have to worry about marketability, hanger appeal, or target audiences. If they go on to work in the industry, they’ll probably never again have the opportunity to be more purely creative in their work.
