Not only does Girlfriend Collective make arguably the best activewear around, they do it ultra-sustainably by transforming post-consumer plastic bottles into super cute sports bras, leggings, bike shorts, and more – all made responsibly in fair and ethical factories. This halter racerback bra is designed with an ultra-soft, extra luxey fabric that offers medium compression and the most comfort for when you have a workout at 5 and a Zoom gala at 5:30.
