Can you wear an official USPS uniform as a costume?

Official, modern USPS uniforms are restricted to actual postal employees. However, creating a generic replica using a light blue shirt, navy pants, and generic postal-style patches is perfectly legal and widely accepted.

What kind of hat does a mailman wear?

Mail carriers typically wear either a navy blue baseball cap, a wide-brimmed sun hat, or a white plastic pith helmet (often called a sun helmet) to protect them from the elements.

How do I make a DIY mailbag?

Take a plain canvas tote bag, attach a long strap so it can be worn crossbody, and write 'U.S. MAIL' on the side with a blue fabric marker or fabric paint.
