Shonda Rhimes, the woman who brought Bridgerton to the screen, has described Penelope's wardrobe as "extraordinary" this season.

"So many times I found myself pausing to really examine her gowns because they were done so exquisitely, and they're so perfectly made for her," Rhimes said in press materials for the show. "It's really, really beautiful."

Penelope has been on "a tremendous journey," Rhimes continued, adding: "I've always loved the character of Penelope. The idea that she's hiding this entire secret life is amazing to me."

"And what I think is great is that we are watching her step into her own this season. She really tries to come into her own, she starts to stand up for herself, and she owns what it means to be Lady Whistledown. I think, for her, it's a tremendous journey."

But Rhimes said that Colin also undergoes an evolution.

"I feel that we watch Colin grow up this season. He's always been very boyish, and this season he becomes a man in so many ways," she said.

"He's been abroad, he's learned some things, and he comes back with a new attitude, but that attitude really gets tested as his feelings for Penelope grow."
