When it comes to dressing sustainably in Hollywood, there’s one fashion whisperer who makes it all possible: Laura Sophie Cox.

The celebrity stylist, who’s dressed everyone from Olivia Rodrigo and Emma Watson to Natalia Reyes, Jacqueline Toboni, Alessia Cara, Janicza Bravo, Grace Gaustad and Luna Blaise, centered her styling business around the ethos of sustainability for over 10 years now, hand-picking vintage pieces and eco-friendly brands for her clients that allow them to evade the dangers of fast-fashion.

“I truly believe that when slow fashion is part of the design process, celebrity dressing takes on a whole new meaning and it challenges the current fashion system,” Cox tells Variety. “And what better way to celebrate these brands than by having strong women and men wear their powerful designs on the red carpet?”

But when working within the confines of rapidly-paced trends, dressing (and styling) ethically can be difficult. What exactly makes a fashion label eco-friendly, and how can consumers make sure they aren’t the victims of false advertising, or greenwashing? Cox warns that people should be wary of trendy buzz words that often don’t offer much more than false promises for sustainability. Phrases like conscious capsule collections, holistic, considered. “What do these words actually mean?” notes Cox. “Do they actually have a track record of caring? Is that campaign being supported by celebrities and influencers that you trust? And did they spend more on production of that campaign than they did in paying their workers?”

These are the kinds of questions Cox asks herself before every fitting and it’s also front of mind for her clients themselves. Emma Watson, for one, is a strong public supporter of the online platform Good On You, a leading source for fashion firm ratings. The same goes for 18 year-old Rodrigo who, according to Cox, already has a strong commitment to sustainable fashion and vintage styling.

Of course, it can be harder to sift through the overwhelming fashion landscape when you don’t have someone doing it for you. So we enlisted Cox, the fashion whisperer herself, to share her favorite sustainable brands and pieces to buy from this summer.

Christopher Kane

Cox says  Christopher Kane is a “go-to” for fittings because of his interesting proportions and silhouettes, whose tailored suits and dresses have been a favorite among stars such as Emma Watson on the red carpet and other public events. But in addition to unique designs, the London-based designer has a good environmental rating, with set science-based targets to reduce greenhouse gases within their operations and supply chain by 50% by 2025.

Maggie Hewitt, the New Zealand-based designer behind the eponymous fashion label, asks one question before every company decision: “Will this be good for the planet and the people?” Hewitt’s vision for a more sustainable and transparent fashion industry is exactly why Cox gravitates towards her bold pieces, which are beloved by clients such as Olivia Rodrigo and Jacqueline Toboni.

Rosie Assoulin

“Rosie Assoulin is unbeatable,” says Cox, who describes the New York fashion company as an electric label with clothes injected with bright dashes of color. Sustainability and ethical designs go hand in hand for the business, where they use local artisans to produce and manufacture their pieces.

Assoulin’s adjustable cropped sweater is a must-have from the designer’s most recent collection. With a classic cable knit that comes in a wide range of colors (choose from yellow and gray and purple, too ), the layered silhouette can be styled in endless ways, such as traditionally off the shoulder or tied around the neck or hem. Plus, it’s made out of merino wool, a biodegradable animal product, that is natural, renewable and doesn’t shed micro-plastics.
