Royal Princess Oud Perfume by Creed, Launched in 2015, royal princess oud is a rich, complex scent that’s fit for a monarch. For thousands of years, oud (also known as agarwood) was prized for its musky, nutty scent and is reportedly one of the most expensive woods in the world. Its oil has traditionally been used as incense and perfume throughout the middle east, but now british perfumer creed has used it to create a modern, east-meets-west fragrance.
