ET caught up with Ridley on the red carpet, where she thanked her "wonderful stylist" for her galactic look.

"My lovely stylist put me in star, what can I say?" she explained, adding that she was a bit anxious before the premiere.

"I was really nervous about an hour ago and then I got here and it was weirdly calm out there. So I was like, 'Oh!' It's all so sweet and quiet and then I come over here and it's like, 'Oh my god! Everybody is shouting and being so loud!' So it took me a second."
