The "Good Girl" star took to Instagram on Saturday and shared a sultry mirror selfie while rocking lacy black lingerie.

"Tell me what this is ASAP I need to buy," Kat Dennings commented.

"CHRISTINA," chimed former "Mad Men" co-star Kiernan Shipka.

"This," added January Jones.

While Hendricks is proud of her coveted curves, she previously noted how the press zeroed in on her body during the height of "Mad Men," which aired from 2007 until 2015. The AMC series, which was set in the ‘60s, detailed the lives of the employees at Sterling Cooper & Partners, a New York City-based advertising firm. The show won 16 Emmys during its seven-year run.

"There certainly was a time when we were very critically acclaimed, and getting a lot of attention for our very good work and our very hard work, and everyone just wanted to ask me about my bra again," Hendricks told The Guardian in June 2021.

"There are only two sentences to say about a bra," she added.

Despite the uncomfortable questions, Hendricks said she was still proud to take on the role of Joan Holloway.

"It may eclipse anything I ever did," she told the outlet. "And, if it does, it was a good one and I’m proud of it. I got to bring who I was as a woman. I think I learned some of how to be a woman from Joan. No one would give a s--t about me if it wasn’t for that show. I’d still be doing good work, but no one would have found me. If that’s the best thing I ever do, it was pretty good."

Hendricks previously reflected on the show’s legacy and weighed in on whether her character was a feminist.

"Some people have called her a feminist, but I would not," Hendricks explained to Entertainment Weekly. "I think she's smart and able. I think she knows that she deserves to be treated in a certain way, but her methods are not technically what you would call 'feminist.' Maybe now you would, but I don't think you would have at the time."

Hendricks is currently filming "The Storied Life of A.J. Fikry" alongside Kunal Nayyar and Lucy Hale.
