Why Was There a Green Costume on ‘I Dream of Jeannie’?

When you think of Barbara Eden as Jeannie, you probably picture her pink costume with the tiny hat, flowing pants and veil, which became part of her signature look on I Dream of Jeannie. But do you also remember the green version?

The green costume was associated with Jeannie’s dark-haired sister, who was also named Jeannie. However, the green costume appeared before her sister was introduced, and Eden wore it as the original Jeannie.
