Livia impressed fashion experts and environmentalists alike throughout the awards season, as she was on a mission to promote sustainable fashion. At the Oscars she looked stunning in a pale pink gown with an organza train, which was constructed from 11 other robes. Her good friend Lucy Siegle has spoken in the past about how radiant Livia looked on the night of the prestigious ceremony.

I turned up at their hotel room to help Livia. But having spent so long talking about the dress I was so completely emotional I just burst into tears. Id bought a pair of white gloves so that when I fastened her up I wouldnt mark the dress but Colin had to help me to a chair where I just cried. This was their moment, but the two of them were ridiculously calm. Colin had to fasten the corsets while I just blubbed like a total drama queen, she said. (C) Cover Media
