There was a special Wonder Woman bikini created.
Designers on the TV series shot for the moon when they tried to develop a two piece Wonder Woman bikini for Carter to wear. They hated how it looked on camera and opted instead for a simple wetsuit. No fashion courses would be made about this piece of TV history.
Diana’s transformation changed after the pilot.
Originally Diana’s transformation into Wonder Woman involved her clothing changing in slow motion. To save time and money they opted to change it after the second episode, opting instead for the famous ball of light.
