Livia Firth's Green Carpet Influence Is Spreading
Livia Firth stepped out in Cannes this weekend, refusing to splurge on a new gown and wearing her mother's 1968 vintage coral dress once modelled by her mother in the Italian resort of Viareggio. Last year, Firth launched her documentary 'The True Cost' Fashion Industry Documentary, featured on AOC one year ago today.
In Cannes Livia dazzled in ethically-sourced emerald jewelry, a collaboration by Chopard and Gemfields, the world's leading producer of colored gemstones. Firth was not alone, joined by Julianne Moore, featured last week wearing Chopard for a David Roemer feature in Grazia Italia.
Moore's emerald earrings are part of the same Chopard and Gemfields collaboration with Llivia Firth.
