Rosie the Riveter
This costume might require you to learn how to fashion a bandana, but that’s the trickiest part. As long as you have a denim top and a red bandana, you are Rosie. You can always go the extra mile and wear a denim jumpsuit instead or find an exact replica of the red bandana with white polka-dots. That’s up to you, how much time you have, and where you plan on going after snapping that Instagram photograph.
