The D23 Expo took over Disneyland, and just like at Comic-Con, there were some incredibly fun and outrageously creative costume ideas for diehard Disney fans. There's something for everyone — cute couple ideas, twists on Disney princesses, and groups from movies like Inside Out (the most popular theme of the event so far). There are even costumes inspired by the rides at Disneyland! Check out our favorites now, and we dare you not to start planning your Halloween costume today.
