Lupita Nyong'o Goes Back To Her Clean Classic Style For Calvin Klein Cannes Party

Lupita Nyong'o is queen of colour blocking, and after that green fringed Prada gown she wore to the Met Gala (no, just no) she's back in her signature Calvin Klein wares.

Lupita attended the IFP, Calvin Klein Collection & Euphoria Calvin Klein celebration of Women In Film in Cannes. Think French chic with a sexy edge.

The 31-year-old Kenyan actress wore a shimmery midnight blue strapless Calvin Klein dress complete with subtle cut-out detailing below the bust and silver heels.

That would be TOTAL SIREN, then. This look on Lupita is amazing and we're all for her sticking to what she does well, colour block dresses and Klein - she killed it last night.

Other ladies working the Cannes circuit last night with Lupita? Oh, just your average A-list line up - Rooney Mara, Naomi Watts and Julianne Moore all in strapless Calvin Klein Collection too, naturally.

Lupita was also working that old #CannesFilmFestival on Instagram last night bringing in her own take on #GlamSquad, check out these photos she posted of herself alongside two very dapper gents.
