Lupita has already made a name for herself as one of the best dressed stars on the red carpet, thanks to her many stylish appearance throughout awards season over the last month.
Last night's turn on the Non-Stop red carpet was no different: Ms Nyong'o looked stunning in a strapless bronze dress by Lanvin with matching metallic Sergio Rossi pumps. The 30-year-old actress topped off her outfit with a clutch by Rauwolf.
Michelle Dockery meanwhile opted for an elegant printed Dior dress for the evening, which she accessorised with Christian Loboutin heels, an Edie Parker clutch and Cartier jewels.
The two actresses looked like they have become firm friends whilst filming their new movie, which also stars Liam Neeson and Julianne Moore, as they giggled together in front of photographers.
Something tells us we're going to be seeing a lot more of these two on the silver screen...
Non-Stop is relased in cinemas on Friday, 28 February
