The 18-year-old Billie Eilish is not only a sensational singer, she is also a passionate vegan who uses her platform to speak about climate change, animal welfare, and the need to be eco-friendly. She often urges her Instagram followers to open their minds to adopt a vegan diet and lifestyle. And just this past January, Eilish authorized H&M to sell her signature oversized clothing and other sustainable merchandise. The line is made from sustainably sourced, non-animal-derived materials. The collection features 16 items with Eilish’s trademark logos and includes printed T-shirts, sweaters, hoodies, bucket hats, a bumbag, and oversized sweatshirts available in her signature colors: beige, black and neon green. “The merch features the official logos of the 18-year-old singer-songwriter in oversized silhouettes and all the clothing has been made from materials sourced in a more sustainable way,” reads the company’s website.
