Oud smells like a deep, complex, and woody scent. Some people describe it as smoky or leathery, and real oud can have a funky or animalic smell, but most fragrances use a smoother, 'western' version. Oud is a powerful ingredient that adds a rich, mysterious vibe to a fragrance. Oud smells like a new, expensive leather jacket mixed with a bonfire, or a dark, woody scent that makes you feel mysterious and intimidating in a good way.
