At Disney, we have offices located all across the company and the nation. Each office (and team for that matter) has its own culture and dress code. Dress in business casual for your first few days until you get a better feel for what others on your team wear. Specific questions should be directed to your leader.
If you work at or otherwise support the Disneyland Resort or Walt Disney World, you are required to adhere to the "Disney Look" for the duration of your internship. Click here for more details on what the Disney Look entails.
