Sustainable fashion is no longer limited to small boutique brands or eco-activists—it’s gone mainstream, thanks in part to high-profile celebrities who are embracing greener choices and redefining red-carpet glam. These style-savvy stars are using their influence to promote ethical production, slow fashion, and conscious consumerism, helping to shift the industry toward a more sustainable future. From upcycled gowns to cruelty-free labels, these celebrities are proving that fashion with a conscience can still make a bold statement.
Here are ten trailblazers redefining fashion with an eco-friendly edge:
Eco-Friendly Celebrities Who Are Fashion Game-Changers
1. Emma Watson
Emma Watson has become one of the most influential voices in sustainable fashion, blending activism with style in a way that feels both aspirational and accessible. A passionate advocate for ethical clothing, she has consistently used her global platform to bring attention to the social and environmental impact of the fashion industry. Rather than just wearing sustainable pieces behind the scenes, Watson makes deliberate choices to wear eco-conscious brands on high-profile red carpets, interviews, and press tours—essentially transforming every public appearance into a style statement with purpose.
A standout initiative is the Instagram account @the_press_tour, launched during the Beauty and the Beast promotional campaign. This platform was created to chronicle fashion choices with a focus on sustainability, each post featuring in-depth captions that reveal the ethical or eco-friendly aspects behind every outfit. From custom gowns crafted with organic materials to ensembles made by brands dedicated to fair labor practices, every look told a story with a purpose. Collaborations with designers like Stella McCartney and brands such as People Tree and Alberta Ferretti’s eco line have helped reshape the definition of high fashion for a more conscious generation. This ongoing dedication continues to inspire consumers to embrace fashion through the dual lenses of sustainability and social responsibility.
2. Billie Eilish
Billie Eilish has emerged as a fearless force in both music and fashion, using her platform to challenge norms and advocate for the planet. Her signature oversized silhouettes and edgy aesthetic are more than just a style choice—they’re part of a broader statement about authenticity, body positivity, and ethical responsibility. A committed vegan, Eilish refuses to wear anything derived from animals, often calling out the environmental and ethical concerns tied to the use of leather, fur, and wool in the fashion industry.
Her influence extends beyond personal choices. In 2020, she launched a vegan and sustainable clothing line in partnership with H&M, using materials like organic cotton and recycled polyester to create fashion that’s both accessible and eco-friendly. One of her most unforgettable moments arrived at the 2021 Met Gala, where she dazzled in a peach Oscar de la Renta gown that captured the essence of Old Hollywood glamour.
But the dress came with a powerful condition: Eilish agreed to wear the gown only if the brand pledged to stop selling fur entirely. They did—and the moment became a symbol of how celebrity influence can drive real change in the fashion world. Eilish continues to speak out about sustainability on tour and in interviews, showing that bold fashion and strong principles can go hand in hand.
3. Zendaya
Zendaya has become a modern style icon with a conscious edge, merging her love for fashion with a commitment to sustainability and social responsibility. Frequently praised for her daring and elegant red carpet looks, she often opts for vintage couture, choosing to breathe new life into archival pieces rather than contributing to the cycle of fast fashion. Whether it’s a 1996 Valentino dress at the NAACP Image Awards or a Y2K Versace moment at the BET Awards, Zendaya proves that timeless fashion can be both sustainable and spectacular.
Her commitment to inclusive and ethical fashion shone brightly in 2019 with the launch of her collaboration, Tommy x Zendaya, alongside Tommy Hilfiger. The collection not only celebrated diversity with a cast of models that spanned various ages, sizes, and backgrounds, but it also incorporated sustainable design principles. The line featured eco-conscious fabrics and thoughtful production methods, showcasing how sustainability and inclusivity can work hand in hand. Beyond her clothing choices, Zendaya has become an advocate for rethinking what fashion can be—intentional, empowering, and environmentally aware. Through her choices, she continues to set a standard for what it means to be stylish with substance.

In a subtle yet powerful move, he chose to wear the same Stella McCartney tuxedo to every major red carpet-event throughout the season. From the Golden Globes to the Oscars, Phoenix’s decision to repeat outfits was a quiet protest against the excess and waste often associated with celebrity fashion, especially during high-profile events where new designer looks are expected at every appearance.
What seemed like a modest gesture ignited a wildfire of dialogue on sustainability and the unyielding demands of consumer culture in showbiz. Phoenix, famed for his veganism and eco-activism, transcended mere fashion—he crafted a bold manifesto. Teaming up with McCartney, a trailblazer in cruelty-free, eco-conscious design, he spotlighted the power of syncing private principles with a public presence.
