Obsessed with W. B. Yeats's epic poem "The Wanderings of Oisin," the perfumer David Seth Moltz traveled to Ireland and Scotland to collect inspiration for HYLNDS, his latest collection for the Brooklyn-based D. S. & Durga. What emerged from his travels are three unisex scents that each evoke the lands in the Celtic myths Yeats drew upon: one is Isle Ryder, an accord of jasmine, gorse and poplar bud that conjures Finlaggan, ruins of a castle in the middle of a lake on the peaty island of Islay. $180; barneys.com.
