Lupita Nyong’o

The 12 Years a Slave winner and fashion "it" girl didn’t disappoint — she wowed in a one-of-a-kind turquoise floral embroidered Gucci gown with custom-dyed Christian Louboutin pumps and vintage Fred Leighton jewels, including a flower ring with rubies, sapphires, emeralds and diamonds from the 1950s.
