The star was thrilled when she first laid eyes on the eagle-like metallic costume, but she quickly realised it would be neither comfortable nor practical to fight in onscreen.
"When we decided to go for another outfit, I was very excited," Gadot told OK! magazine. "And when (director) Patty Jenkins showed me what we were going for, I was stoked."
"I thought the costume looked fantastic, but it didn't look comfortable at all. I was like, 'OK, how do we make the golden one practical and comfortable?' Well, it wasn't. But it looks great and it was worth the pain!"
The Israeli beauty was no stranger to the superhero's uncomfortable outfits - she previously hid the fact she could barely breathe in Wonder Woman's corset-style costume when she was initially cast as the DC Comics icon and her alter ego, Diana Prince.
"Two days after they cast me for the role, they brought me to Michigan to do the fittings," she recalled.
"I walked into this huge room where there were tons of images of me as Wonder Woman. They got me into the fitting room and I put on the costume, which was crazy."
"I was so grateful, thankful, and happy to be there that I didn't say a word about the fact that the costume was incredibly small and tight. I just kept saying, 'Thank you for having me.' And then I started to breathe really heavily and couldn't really speak, so the designer did lots of adjustments!"
