Latasha Rose's (Portia) interview with S2S Magazine. She discuses playing Peeta's stylist and working with Lenny Kravitz.

"Booking one of the most highly anticipated gigs in Hollywood is no easy feat, but when you’ve got to basically create your character from the ground up, it presents a whole new challenge.
As it turns out, Latarsha was more than up to the task for her role as Hunger Gamesstylist Portia. She’s half the team tasked with creating memorable looks for District 12 Tributes Katniss Everdeen and Peeta Mellark. Portia works alongside Cinna (played by Lenny Kravitz) to pull off the super-glam, slightly incendiary ensembles.
Lenny had a lot to work with because Cinna had a lot of dialogue in The Hunger Gamesand his relationship with Katniss was more fleshed out. Latarsha, on the other hand, didn’t have as much to go on. Although Portia is an important part of the story (she works more closely with Peeta), she doesn’t speak very much.
So where did that leave Latarsha when figuring out how to play Portia? “The only way that I had was to really read the books and then use my imagination,” she explained to S2S. “It’s a mini collaboration with myself, the book and then the actual film.”
Latarsha quickly found out that her vision for Portia was on target with what the production behind The Hunger Games had in mind.
“There were things that came to me—ideas and mannerisms and colors and the way she might dress,” Latarsha said. “I was happily surprised that when I got there the vision of the amazing team…it meshed.”
While Cinna is very fond of simple, classic style (he’s never not wearing black), Portia is a little more partial to the over-the-top clothing of The Capitol. That means that she could be wearing anything that couturier’s fevered imagination could possibly dream up.
“I’m not really recognizable once I step into Portia,” Latarsha said, without giving too much of her look away. “I think she’s very much a fashionista and very grand but sophisticated. I believe Portia’s a complement to Cinna.”
She continued, “There are outfits of mine that were, I thought, quite phenomenal and helped me sort of really get into character.”
