Superhero landings, wire fights, explosions—costumes don't just look good; they have to perform. ISBCD costume designers Gersha Phillips (Captain America), Trayce Gigi Field (Spider-Noir), Charlese Antoinette (Children of Blood and Bone), Antoinette Messam (The Bluff), Dominique Dawson (HIM), Tiffany Hasbourne (Shadow Force), and Jennifer Bryan (The Acolyte) break down how garments are engineered for extreme action, from stretch fabrics and hidden reinforcements to quick-change duplicates and stunt doubles. The panel shares stories of costumes that ripped, burned, or had to be rebuilt overnight, and how teams saved the day.
