Founded in 2009 by Mary Jane Chon in Los Angeles, Mono B began as a young contemporary label before pivoting entirely to activewear and athleisure in 2015. The brand has built a robust wholesale and direct-to-consumer presence by offering functional, trend-conscious performance wear at an accessible price point. Mono B’s core product lines—ranging from seamless leggings and supportive sports bras to relaxed loungewear—are designed with a focus on comfort, versatility, and everyday movement. The aesthetic leans minimal and sporty, prioritizing flattering fits and practical details over loud branding.
