ONE AND ONLY: While H&M is known for its collaborations with famous designers like Karl Lagerfeld, Stella McCartney and Comme des Garcons, things are a little different in their new store in Berlin’s hip Hackesche Markt neighborhood. In a collaboration with the young Berlin designer duo C.neeon, H&M is offering 300 limited edition T-shirts in C.neeon’s signature geometric patterns. The T-shirts retail at 24.99 euros or about $34.50 at current exchange, and all proceeds will go to Berliner Tafel E.V., a charity which provides food for the homeless. “It all started when they asked us if we could do some illustrations for the walls, and then came the idea for the charity T-shirts,” said C.neeon designer Doreen Schulz. Schulz and her partner Clara Leskovar have shown c.Neeon internationally and the brand has also sold to Topshop. The 5,400-square-foot H&M unit is spread over two levels and has a cool, contemporary art gallery vibe in tune with its neighborhood.
