Lupita Nyong'o is non-stop! The Oscar nominee stepped up her red carpet game once again when she attended the Women in Film Pre-Oscar party at Fig & Olive in L.A. on Friday, Feb. 28.

At the event, Nyong'o, 30, wore a gorgeous Michael Kors cut-out dress that showed off her toned abs and svelte figure. She paired the chic look with royal blue Pedro Garcia stilettos and simple Graziela Gems jewelry.

The 12 Years a Slave actress walked the red carpet with Helen Mirren, and fellow Oscar nominee June Squibb. Nyong'o also brought along her mother Dorothy as her date.

Nyong'o's awards season style has been just as impressive as her acting skills. In an interview with The Daily Beast last month, the first-time Oscar nominee admitted her fashion sense didn't come naturally.

"Until all this, I hadn't been a student of the fashion industry as a formal industry," she said. "I wasn't the girl who bought the fashion magazines, I'd always just worn what appeals to me."

She continued: "When I knew I was going to be doing the press tour for 12 Years A Slave, I got to work and started researching what was happening in the formal world of fashion to try and articulate to myself what my style would be in it all."
