In 2012, Rastam founded Dahsar, the contemporary whateverwear brand, publication, and creative design studio. Simpler Times.

Dahsar means simpler times. Rastam created Dahsar and made clothes because it was a creative output where he combined many hats he cut his teeth from such as being a buyer for a BMX streetwear shop, designer for a creative agency, and a consultant in fashion, all in one.
