The 31-year-old Oscar winner had the dress inside her hotel room at The London in West Hollywood, Calif., when it was lifted sometime between 8 AM and 9 PM on Tuesday, February 24. The dress featured 6,000 Akoya pearls and landed Nyong'o a spot on many best dressed lists for the night. 

TMZ reports that hotel security footage could possibly lead to the identification and capture of the thief.
