Avocado - Olive 1930’s Bandana Our signature OZMA bandanas and hankies elevate the classic form, each made from 100% silk and designed in a soft, earthy palette inspired by the wild and rugged beauty of California. Our silk bandanas are screen printed by hand and dyed in small batches locally in Los Angeles. Slight variations are inherent to the process, and add to the unique beauty of the product.
