Oh, Jessica Chastain, you are a precious gem.
The actress took to the stage with James Franco at the Chime for Change: Sound of Change Live concert in London on Saturday, looking effortlessly gorgeous in a black Gucci dress with a web-like lace yoke.
She added some zest to the outfit with silver spiked Christian Louboutin pumps and smartly styled her hair in cascading waves yet again.
Next to her acting talent, we'd say her locks are the most enviable thing about her!
Isn't she the BESTEST?!
