Girlfriend Collective

Girlfriend Collective

Quick history

Girlfriend Collective was founded in 2016 in the United States as an activewear brand built around transparency, sustainability, and inclusive sizing. The brand gained early attention for using recycled materials—most notably post-consumer water bottles—to produce leggings and sports bras, while openly sharing details about its factories, wages, and supply chain. With minimalist design and a values-forward approach, Girlfriend Collective positioned itself as an alternative to traditional performance wear brands.
