Lily James was in her best outfit ever for her Jimmy Kimmel Live interview with Pam & Tommy co-star Sebastian Stan.

The actress, who plays Pamela Anderson on the TV series, wore a chic all-black ensemble by Magda Buttrim (via Daily Mail), including a chiffon, floral crop top (open with new tab) and wide silk pants, with simple pointed black heeled pumps.

As she headed to and from the television, she added a pair of small 90s-style black sunglasses and a black blazer to complete the look. She wore her balayage hair down.

James recently spoke to Entertainment Weekly about how the team transformed her into Pamela Anderson for the show.

"I sat in the makeup chair at 3:30 a.m. and spent four hours transforming into Pamela. There was the eyes, the wig, the teeth, the whole process."

Obviously, James and Anderson look nothing alike in real life, so it makes sense that the actress had to go through such a daunting transformation. 'We looked at several different prostheses for the nose, chin, eyebrows, forehead, etc., but in the end we cut them down as much as possible,'

Anderson said. We didn't want to create too much of a barrier between me and my look." I think they did a really great job. I was really blown away by what they were able to do."

But it wasn't just the makeup: she also had to train harder than I ever had in my life for the role. She said, "I worked with a great trainer, Matt Bevan, who also worked with Daisy Ridley. He worked me very hard and I got really fit. I lost a lot of weight. But unfortunately, I gained it back. But I've gained a lot of confidence because I hadn't exercised in a long time. I feel less self-conscious on the beach. Well, I hope she's happy.

Pam and Tommy premiered on Hulu on February 2.
