Rachel channels revenge dress on first red carpet without Siya Kolisi

Speaking to IOL, Kolisi shared that the dress was in celebration of the green carpet's call to embrace sustainability with her stylist, Georgina Rae Bennet, picking out the dress from Style Rotate, who offer rental gowns to encourage the reuse of dresses rather than buying new ones.

“They're saving our planet one dress at a time,” said Kolisi. “Materials and dresses are being made on a daily basis and fashion is just moving faster and faster so if we all just start making small changes wherever we can, we're going to have a huge impact on our environment. So, we're just going to have to get intentional about it.”

Kolisis also stunned in her separate look for one of her sessions for Earthshot with a much more modern look. The boxy suit set featured a jacket from upcycling company Rethread which featured an oversized suit cinched at the waist with a grey fabric that matched her wide-legged retail trousers. To finish the look she added white pointed toe Steve Madden heels, a handbag from Nigerian-based designer Mairachamp and Yellow by Jeslea brooch which champions ethically-sourced metals.
