Mainline was founded in 2019 by London-based duo Zarina Bekerova and Alexandra Vincent. The main focus of the brand is to forge a visual language that reconciles and articulates instances of fluid placelessness while exploring societal juxtapositions of comfort and sexiness. Features include 100% cotton construction, a slim fit, ribbed collar, draped design, and decorative darts and rivets at the front and back.
