In 2006, together with her partner David Røgilds, a Danish graphic artist and designer, she established the fashion business Bibi Chemnitz in Aarhus, moving to Copenhagen in 2012.[2] The firm markets fashions for both men and women through retailers around the world, including Galeries Lafayette, Beijing, the Koon department store in Seoul, and Podium Market in Moscow. Over the years, designs have been exhibited at fashion weeks throughout Europe and beyond.[4] Inspired by her Native heritage, Chemnitz combines Danish trends with Greenlandic patterns in her hats and prints, benefiting from Nordic minimalism. She also designs fashions which are suited to customers in countries such as India and China.[2] These include Chemnitz' innovative shapes and carefully tailored leisurewear.[5] As a result, she has become something of a star in Greenland although she prefers to avoid the limelight.[3]
In 2023, Chemnitz has exhibited in Paris and, hoping to develop marketing to Asia, in China and Japan.[6]
As in 2019, always happy to be back in Greenland, Chemnitz is a key participant at the 2023 Nuuk Nordic Cultural Festival, designing a variety of hats, tee-shirts, scarves and bags to fit the festival's needs.[6]
