The story behind the bottle.
I Don’t Know What by DS&Durga, launched in 2018 and crafted by David Seth Moltz, is a fragrance enhancer that embodies the elusive quality of 'je ne sais quoi.' The composition opens with bright bergamot before diving into Iso E Super and vetiver, creating a tension between freshness and earthiness. The base notes of sandalwood, amber, and synthetic civet add warmth and depth, giving it an animalic edge that lingers on the skin.
Apply this fragrance in layers for the best effect — start with a light spritz to let the top notes shine, then add another layer after 15 minutes as the heart notes begin to emerge. The amber and musk base will continue to develop throughout the day.
