Career

Around 13 years after launching Moana Bikini, she expanded her business with The Moana Smile Club, a sister brand offering activewear and accessories that uphold the same empowering values.

In addition to fashion, Karina co-founded Bikini Body Burn, a fitness and nutrition guide designed to help women achieve their best health in a sustainable way. This project evolved naturally from her swimwear customers’ interest in fitness.
