The Oscar-winner looked breathtaking in a kooky green '20s-inspired Prada as she made her way up the famous Met red carpeted steps and blew everyone away with her grace and beauty.
Wearing a matching satin headband on her hair which was styled into a bun, the 31-year-old looked ready to party in the frock, which featured delicate beading over netted fabric, green feathers and a brown underlay.
Matching green jewelled shoes and a box clutch completed the ensemble but the night was just starting for the "12 Years A Slave" star who is quickly becoming one of the A-listers to watch on the red carpet.
Lupita also wore Prada at the 2014 Oscars so it's no surprise that she went with the brand again. What do you think? Best dressed of the night? We're going to go with a resounding YES.
