You would be forgiven for thinking that Girlfriend Collective are a new progressive girl band. We did. Until we realised they are actually a Seattle-based activewear company, whose leggings nearly broke the internet, when they began giving them away for free in 2016. Each pair of their stretchy pants is made from 25 plastic bottles. That said, it's as though this group of girls is in perfect harmony and pitched perfect for the current conscious fashion climate.
