Start small: build a silhouette that reads from a distance and you’ve already solved half the problem. I like to sketch five or six very different silhouettes for a single character—big coat, tight suit, flowing dress, bulky armor—and immediately I can tell which ones fit the character’s energy. Shapes tell personality: roundness feels friendly, sharp angles feel aggressive, and long vertical lines feel elegant.
Next I think about fabric behavior and how it interacts with movement. If your cartoon person is a dancer, give them flowing skirts or loose sleeves; if they’re a brawler, think reinforced seams and visible patches. Use a palette of three to five colors: a dominant, a secondary, and one or two accents for contrast. Patterns and trims should respect scale—tiny floral prints vanish at a distance, bold stripes read well. I study shows like 'The Incredibles' for silhouette clarity and 'Studio Ghibli' for how costume detail hints at worldbuilding. Finally, make thumbnails, pick one, then iterate—change a collar, swap boots for sneakers, test in a few poses. I love that moment when a few scribbles start to feel like a real person; it never gets old.
