Calvin Klein Collection customers at the Madison Avenue store are able to buy from this week unique floral arrangements by Lauren Messelian.

The artist collaborates regularly with the brand on the store’s iconic floral installations as well as those in CALVIN KLEIN‘s office and events.

Initially trained in fine arts at the University of Michigan, Messelian later continued her studies in Paris at Atelier 63 before moving back to New York City where she began to work with flowers.

The pieces she’s made for Calvin Klein Collection are described as “portable living sculptures, uniting art and design” and they feature succulent greens and stones captured in angular glass.

The curated floristry will be available from now through December 24, on the main floor of the store.

Messelian’s other high-profile fashion and arts clients and collaborators include Roger Vivier, Tods, Stella McCartney, Rachel Zoe, Michael Kors, Frye, Tory Burch, and the Guggenheim Museum.
